    Ubiquitin is phosphorylated by PINK1 to activate parkin (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-05-03
    Description: PINK1 (PTEN induced putative kinase 1) and PARKIN (also known as PARK2) have been identified as the causal genes responsible for hereditary recessive early-onset Parkinsonism. PINK1 is a Ser/Thr kinase that specifically accumulates on depolarized mitochondria, whereas parkin is an E3 ubiquitin ligase that catalyses ubiquitin transfer to mitochondrial substrates. PINK1 acts as an upstream factor for parkin and is essential both for the activation of latent E3 parkin activity and for recruiting parkin onto depolarized mitochondria. Recently, mechanistic insights into mitochondrial quality control mediated by PINK1 and parkin have been revealed, and PINK1-dependent phosphorylation of parkin has been reported. However, the requirement of PINK1 for parkin activation was not bypassed by phosphomimetic parkin mutation, and how PINK1 accelerates the E3 activity of parkin on damaged mitochondria is still obscure. Here we report that ubiquitin is the genuine substrate of PINK1. PINK1 phosphorylated ubiquitin at Ser 65 both in vitro and in cells, and a Ser 65 phosphopeptide derived from endogenous ubiquitin was only detected in cells in the presence of PINK1 and following a decrease in mitochondrial membrane potential. Unexpectedly, phosphomimetic ubiquitin bypassed PINK1-dependent activation of a phosphomimetic parkin mutant in cells. Furthermore, phosphomimetic ubiquitin accelerates discharge of the thioester conjugate formed by UBCH7 (also known as UBE2L3) and ubiquitin (UBCH7 approximately ubiquitin) in the presence of parkin in vitro, indicating that it acts allosterically. The phosphorylation-dependent interaction between ubiquitin and parkin suggests that phosphorylated ubiquitin unlocks autoinhibition of the catalytic cysteine. Our results show that PINK1-dependent phosphorylation of both parkin and ubiquitin is sufficient for full activation of parkin E3 activity. These findings demonstrate that phosphorylated ubiquitin is a parkin activator.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koyano, Fumika -- Okatsu, Kei -- Kosako, Hidetaka -- Tamura, Yasushi -- Go, Etsu -- Kimura, Mayumi -- Kimura, Yoko -- Tsuchiya, Hikaru -- Yoshihara, Hidehito -- Hirokawa, Takatsugu -- Endo, Toshiya -- Fon, Edward A -- Trempe, Jean-Francois -- Saeki, Yasushi -- Tanaka, Keiji -- Matsuda, Noriyuki -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2014 Jun 5;510(7503):162-6. doi: 10.1038/nature13392.

    Proviral silencing in embryonic stem cells requires the histone methyltransferase ESET (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-02-19
    Description: Endogenous retroviruses (ERVs), retrovirus-like elements with long terminal repeats, are widely dispersed in the euchromatic compartment in mammalian cells, comprising approximately 10% of the mouse genome. These parasitic elements are responsible for 〉10% of spontaneous mutations. Whereas DNA methylation has an important role in proviral silencing in somatic and germ-lineage cells, an additional DNA-methylation-independent pathway also functions in embryonal carcinoma and embryonic stem (ES) cells to inhibit transcription of the exogenous gammaretrovirus murine leukaemia virus (MLV). Notably, a recent genome-wide study revealed that ERVs are also marked by histone H3 lysine 9 trimethylation (H3K9me3) and H4K20me3 in ES cells but not in mouse embryonic fibroblasts. However, the role that these marks have in proviral silencing remains unexplored. Here we show that the H3K9 methyltransferase ESET (also called SETDB1 or KMT1E) and the Kruppel-associated box (KRAB)-associated protein 1 (KAP1, also called TRIM28) are required for H3K9me3 and silencing of endogenous and introduced retroviruses specifically in mouse ES cells. Furthermore, whereas ESET enzymatic activity is crucial for HP1 binding and efficient proviral silencing, the H4K20 methyltransferases Suv420h1 and Suv420h2 are dispensable for silencing. Notably, in DNA methyltransferase triple knockout (Dnmt1(-/-)Dnmt3a(-/-)Dnmt3b(-/-)) mouse ES cells, ESET and KAP1 binding and ESET-mediated H3K9me3 are maintained and ERVs are minimally derepressed. We propose that a DNA-methylation-independent pathway involving KAP1 and ESET/ESET-mediated H3K9me3 is required for proviral silencing during the period early in embryogenesis when DNA methylation is dynamically reprogrammed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsui, Toshiyuki -- Leung, Danny -- Miyashita, Hiroki -- Maksakova, Irina A -- Miyachi, Hitoshi -- Kimura, Hiroshi -- Tachibana, Makoto -- Lorincz, Matthew C -- Shinkai, Yoichi -- 77805/Canadian Institutes of Health Research/Canada -- 92090/Canadian Institutes of Health Research/Canada -- England -- Nature. 2010 Apr 8;464(7290):927-31. doi: 10.1038/nature08858.

    Nebulin and N-WASP cooperate to cause IGF-1-induced sarcomeric actin filament formation (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-12-15
    Description: Insulin-like growth factor 1 (IGF-1) induces skeletal muscle maturation and enlargement (hypertrophy). These responses require protein synthesis and myofibril formation (myofibrillogenesis). However, the signaling mechanisms of myofibrillogenesis remain obscure. We found that IGF-1-induced phosphatidylinositol 3-kinase-Akt signaling formed a complex of nebulin and N-WASP at the Z bands of myofibrils by interfering with glycogen synthase kinase-3beta in mice. Although N-WASP is known to be an activator of the Arp2/3 complex to form branched actin filaments, the nebulin-N-WASP complex caused actin nucleation for unbranched actin filament formation from the Z bands without the Arp2/3 complex. Furthermore, N-WASP was required for IGF-1-induced muscle hypertrophy. These findings present the mechanisms of IGF-1-induced actin filament formation in myofibrillogenesis required for muscle maturation and hypertrophy and a mechanism of actin nucleation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takano, Kazunori -- Watanabe-Takano, Haruko -- Suetsugu, Shiro -- Kurita, Souichi -- Tsujita, Kazuya -- Kimura, Sumiko -- Karatsu, Takashi -- Takenawa, Tadaomi -- Endo, Takeshi -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1536-40. doi: 10.1126/science.1197767.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Graduate School of Science, Chiba University, 1-33 Yayoicho, Inageku, Chiba 263-8522, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148390" target="_blank"〉PubMed〈/a〉

    Positive feedback within a kinase signaling complex functions as a switch mechanism for NF-kappaB activation (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-05-17
    Description: A switchlike response in nuclear factor-kappaB (NF-kappaB) activity implies the existence of a threshold in the NF-kappaB signaling module. We show that the CARD-containing MAGUK protein 1 (CARMA1, also called CARD11)-TAK1 (MAP3K7)-inhibitor of NF-kappaB (IkappaB) kinase-beta (IKKbeta) module is a switch mechanism for NF-kappaB activation in B cell receptor (BCR) signaling. Experimental and mathematical modeling analyses showed that IKK activity is regulated by positive feedback from IKKbeta to TAK1, generating a steep dose response to BCR stimulation. Mutation of the scaffolding protein CARMA1 at serine-578, an IKKbeta target, abrogated not only late TAK1 activity, but also the switchlike activation of NF-kappaB in single cells, suggesting that phosphorylation of this residue accounts for the feedback.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shinohara, Hisaaki -- Behar, Marcelo -- Inoue, Kentaro -- Hiroshima, Michio -- Yasuda, Tomoharu -- Nagashima, Takeshi -- Kimura, Shuhei -- Sanjo, Hideki -- Maeda, Shiori -- Yumoto, Noriko -- Ki, Sewon -- Akira, Shizuo -- Sako, Yasushi -- Hoffmann, Alexander -- Kurosaki, Tomohiro -- Okada-Hatakeyama, Mariko -- 5R01CA141722/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2014 May 16;344(6185):760-4. doi: 10.1126/science.1250020.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Integrated Cellular Systems, RIKEN Center for Integrative Medical Sciences (IMS-RCAI), Tsurumi-ku, Yokohama, Kanagawa 230-0045, Japan. ; Signaling Systems Laboratory, Department of Chemistry and Biochemistry, University of California, San Diego, La Jolla, CA 92093, USA.

    Sema3A regulates bone-mass accrual through sensory innervations (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-05-07
    Description: Semaphorin 3A (Sema3A) is a diffusible axonal chemorepellent that has an important role in axon guidance. Previous studies have demonstrated that Sema3a(-/-) mice have multiple developmental defects due to abnormal neuronal innervations. Here we show in mice that Sema3A is abundantly expressed in bone, and cell-based assays showed that Sema3A affected osteoblast differentiation in a cell-autonomous fashion. Accordingly, Sema3a(-/-) mice had a low bone mass due to decreased bone formation. However, osteoblast-specific Sema3A-deficient mice (Sema3acol1(-/-) and Sema3aosx(-/-) mice) had normal bone mass, even though the expression of Sema3A in bone was substantially decreased. In contrast, mice lacking Sema3A in neurons (Sema3asynapsin(-/-) and Sema3anestin(-/-) mice) had low bone mass, similar to Sema3a(-/-) mice, indicating that neuron-derived Sema3A is responsible for the observed bone abnormalities independent of the local effect of Sema3A in bone. Indeed, the number of sensory innervations of trabecular bone was significantly decreased in Sema3asynapsin(-/-) mice, whereas sympathetic innervations of trabecular bone were unchanged. Moreover, ablating sensory nerves decreased bone mass in wild-type mice, whereas it did not reduce the low bone mass in Sema3anestin(-/-) mice further, supporting the essential role of the sensory nervous system in normal bone homeostasis. Finally, neuronal abnormalities in Sema3a(-/-) mice, such as olfactory development, were identified in Sema3asynasin(-/-) mice, demonstrating that neuron-derived Sema3A contributes to the abnormal neural development seen in Sema3a(-/-) mice, and indicating that Sema3A produced in neurons regulates neural development in an autocrine manner. This study demonstrates that Sema3A regulates bone remodelling indirectly by modulating sensory nerve development, but not directly by acting on osteoblasts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fukuda, Toru -- Takeda, Shu -- Xu, Ren -- Ochi, Hiroki -- Sunamura, Satoko -- Sato, Tsuyoshi -- Shibata, Shinsuke -- Yoshida, Yutaka -- Gu, Zirong -- Kimura, Ayako -- Ma, Chengshan -- Xu, Cheng -- Bando, Waka -- Fujita, Koji -- Shinomiya, Kenichi -- Hirai, Takashi -- Asou, Yoshinori -- Enomoto, Mitsuhiro -- Okano, Hideyuki -- Okawa, Atsushi -- Itoh, Hiroshi -- NS065048/NS/NINDS NIH HHS/ -- England -- Nature. 2013 May 23;497(7450):490-3. doi: 10.1038/nature12115.

    A small-molecule AdipoR agonist for type 2 diabetes and short life in obesity (2013)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2013-11-01
    Description: Adiponectin secreted from adipocytes binds to adiponectin receptors AdipoR1 and AdipoR2, and exerts antidiabetic effects via activation of AMPK and PPAR-alpha pathways, respectively. Levels of adiponectin in plasma are reduced in obesity, which causes insulin resistance and type 2 diabetes. Thus, orally active small molecules that bind to and activate AdipoR1 and AdipoR2 could ameliorate obesity-related diseases such as type 2 diabetes. Here we report the identification of orally active synthetic small-molecule AdipoR agonists. One of these compounds, AdipoR agonist (AdipoRon), bound to both AdipoR1 and AdipoR2 in vitro. AdipoRon showed very similar effects to adiponectin in muscle and liver, such as activation of AMPK and PPAR-alpha pathways, and ameliorated insulin resistance and glucose intolerance in mice fed a high-fat diet, which was completely obliterated in AdipoR1 and AdipoR2 double-knockout mice. Moreover, AdipoRon ameliorated diabetes of genetically obese rodent model db/db mice, and prolonged the shortened lifespan of db/db mice on a high-fat diet. Thus, orally active AdipoR agonists such as AdipoRon are a promising therapeutic approach for the treatment of obesity-related diseases such as type 2 diabetes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okada-Iwabu, Miki -- Yamauchi, Toshimasa -- Iwabu, Masato -- Honma, Teruki -- Hamagami, Ken-ichi -- Matsuda, Koichi -- Yamaguchi, Mamiko -- Tanabe, Hiroaki -- Kimura-Someya, Tomomi -- Shirouzu, Mikako -- Ogata, Hitomi -- Tokuyama, Kumpei -- Ueki, Kohjiro -- Nagano, Tetsuo -- Tanaka, Akiko -- Yokoyama, Shigeyuki -- Kadowaki, Takashi -- England -- Nature. 2013 Nov 28;503(7477):493-9. doi: 10.1038/nature12656.

The lack of disease models using human cells has hampered the identification of a clinically effective treatment for these diseases. Here we show that statin treatment can rescue patient-specific induced pluripotent stem cell (iPSC) models and a mouse model of FGFR3 skeletal dysplasia. We converted fibroblasts from thanatophoric dysplasia type I (TD1) and ACH patients into iPSCs. The chondrogenic differentiation of TD1 iPSCs and ACH iPSCs resulted in the formation of degraded cartilage. We found that statins could correct the degraded cartilage in both chondrogenically differentiated TD1 and ACH iPSCs. Treatment of ACH model mice with statin led to a significant recovery of bone growth. These results suggest that statins could represent a medical treatment for infants and children with TD1 and ACH.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamashita, Akihiro -- Morioka, Miho -- Kishi, Hiromi -- Kimura, Takeshi -- Yahara, Yasuhito -- Okada, Minoru -- Fujita, Kaori -- Sawai, Hideaki -- Ikegawa, Shiro -- Tsumaki, Noriyuki -- England -- Nature. 2014 Sep 25;513(7519):507-11. doi: 10.1038/nature13775.
