    Dynamic control of CaMKII translocation and localization in hippocampal neurons by NMDA receptor stimulation (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-04-02
    Description: Calcium-calmodulin-dependent protein kinase II (CaMKII) is thought to increase synaptic strength by phosphorylating postsynaptic density (PSD) ion channels and signaling proteins. It is shown that N-methyl-D-aspartate (NMDA) receptor stimulation reversibly translocates green fluorescent protein-tagged CaMKII from an F-actin-bound to a PSD-bound state. The translocation time was controlled by the ratio of expressed beta-CaMKII to alpha-CaMKII isoforms. Although F-actin dissociation into the cytosol required autophosphorylation of or calcium-calmodulin binding to beta-CaMKII, PSD translocation required binding of calcium-calmodulin to either the alpha- or beta-CaMKII subunits. Autophosphorylation of CaMKII indirectly prolongs its PSD localization by increasing the calmodulin-binding affinity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, K -- Meyer, T -- GM-48113/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1999 Apr 2;284(5411):162-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology and Department of Pharmacology and Cancer Biology, Box 3709, Duke University Medical Center, Durham, NC 27710, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10102820" target="_blank"〉PubMed〈/a〉

    Primary structure of the beta subunit of the DHP-sensitive calcium channel from skeletal muscle (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-09-08
    Description: Complementary DNAs for the beta subunit of the dihydropyridine-sensitive calcium channel of rabbit skeletal muscle were isolated on the basis of peptide sequences derived from the purified protein. The deduced primary structure is without homology to other known protein sequences and is consistent with the beta subunit being a peripheral membrane protein associated with the cytoplasmic aspect of the sarcolemma. The protein contains sites that might be expected to be preferentially phosphorylated by protein kinase C and guanosine 3',5'-monophosphate-dependent protein kinase. A messenger RNA for this protein appears to be expressed in brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ruth, P -- Rohrkasten, A -- Biel, M -- Bosse, E -- Regulla, S -- Meyer, H E -- Flockerzi, V -- Hofmann, F -- New York, N.Y. -- Science. 1989 Sep 8;245(4922):1115-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Physiologische Chemie, Medizinische Fakultat, Homburg/Saar, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2549640" target="_blank"〉PubMed〈/a〉

    Calmodulin trapping by calcium-calmodulin-dependent protein kinase (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-05-22
    Description: Multifunctional calcium-calmodulin-dependent protein kinase (CaM kinase) transduces transient elevations in intracellular calcium into changes in the phosphorylation state and activity of target proteins. By fluorescence emission anisotropy, the affinity of CaM kinase for dansylated calmodulin was measured and found to increase 1000 times after autophosphorylation of the threonine at position 286 of the protein. Autophosphorylation markedly slowed the release of bound calcium-calmodulin; the release time increased from less than a second to several hundred seconds. In essence, calmodulin is trapped by autophosphorylation. The shift in affinity does not occur in a site-directed mutant in which threonine at position 286 has been replaced by a non-phosphorylatable amino acid. These experiments demonstrate the existence of a new state in which calmodulin is bound to CaM kinase even though the concentration of calcium is basal. Calmodulin trapping provides for molecular potentiation of calcium transients and may enable detection of their frequency.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, T -- Hanson, P I -- Stryer, L -- Schulman, H -- GM 40600/GM/NIGMS NIH HHS/ -- GM24032/GM/NIGMS NIH HHS/ -- MH45324/MH/NIMH NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1992 May 22;256(5060):1199-202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Stanford University School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1317063" target="_blank"〉PubMed〈/a〉

    Enhanced DNA-binding activity of a Stat3-related protein in cells transformed by the Src oncoprotein (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-07-07
    Description: Cytokines and growth factors induce tyrosine phosphorylation of signal transducers and activators of transcription (STATs) that directly activate gene expression. Cells stably transformed by the Src oncogene tyrosine kinase were examined for STAT protein activation. Assays of electrophoretic mobility, DNA-binding specificity, and antigenicity indicated that Stat3 or a closely related STAT family member was constitutively activated by the Src oncoprotein. Induction of this DNA-binding activity was accompanied by tyrosine phosphorylation of Stat3 and correlated with Src transformation. These findings demonstrate that Src can activate STAT signaling pathways and raise the possibility that Stat3 contributes to oncogenesis by Src.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yu, C L -- Meyer, D J -- Campbell, G S -- Larner, A C -- Carter-Su, C -- Schwartz, J -- Jove, R -- CA55652/CA/NCI NIH HHS/ -- DK34171/DK/NIDDK NIH HHS/ -- R01 DK034171/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1995 Jul 7;269(5220):81-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of Michigan Medical School, Ann Arbor 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7541555" target="_blank"〉PubMed〈/a〉

    Rapid chemically induced changes of PtdIns(4,5)P2 gate KCNQ ion channels (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-09-23
    Description: To resolve the controversy about messengers regulating KCNQ ion channels during phospholipase C-mediated suppression of current, we designed translocatable enzymes that quickly alter the phosphoinositide composition of the plasma membrane after application of a chemical cue. The KCNQ current falls rapidly to zero when phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2 or PI(4,5)P2] is depleted without changing Ca2+, diacylglycerol, or inositol 1,4,5-trisphosphate. Current rises by 30% when PI(4,5)P2 is overproduced and does not change when phosphatidylinositol 3,4,5-trisphosphate is raised. Hence, the depletion of PI(4,5)P2 suffices to suppress current fully, and other second messengers are not needed. Our approach is ideally suited to study biological signaling networks involving membrane phosphoinositides.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3579521/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3579521/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suh, Byung-Chang -- Inoue, Takanari -- Meyer, Tobias -- Hille, Bertil -- AR17803/AR/NIAMS NIH HHS/ -- GM63702/GM/NIGMS NIH HHS/ -- MH64801/MH/NIMH NIH HHS/ -- NS08174/NS/NINDS NIH HHS/ -- R01 GM030179/GM/NIGMS NIH HHS/ -- R01 GM030179-24A1/GM/NIGMS NIH HHS/ -- R01 GM030179-25/GM/NIGMS NIH HHS/ -- R01 GM063702/GM/NIGMS NIH HHS/ -- R01 MH064801/MH/NIMH NIH HHS/ -- R01 NS008174/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2006 Dec 1;314(5804):1454-7.
