    Structural basis for the activation of cholera toxin by human ARF6-GTP (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-08-16
    Description: The Vibrio cholerae bacterium causes devastating diarrhea when it infects the human intestine. The key event is adenosine diphosphate (ADP)-ribosylation of the human signaling protein GSalpha, catalyzed by the cholera toxin A1 subunit (CTA1). This reaction is allosterically activated by human ADP-ribosylation factors (ARFs), a family of essential and ubiquitous G proteins. Crystal structures of a CTA1:ARF6-GTP (guanosine triphosphate) complex reveal that binding of the human activator elicits dramatic changes in CTA1 loop regions that allow nicotinamide adenine dinucleotide (NAD+) to bind to the active site. The extensive toxin:ARF-GTP interface surface mimics ARF-GTP recognition of normal cellular protein partners, which suggests that the toxin has evolved to exploit promiscuous binding properties of ARFs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Neal, Claire J -- Jobling, Michael G -- Holmes, Randall K -- Hol, Wim G J -- AI-31940/AI/NIAID NIH HHS/ -- AI-34501/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2005 Aug 12;309(5737):1093-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16099990" target="_blank"〉PubMed〈/a〉

    Notes: Summary A peptide hormone was extracted from the porcine right atrium following a bioassay for differential vaso-relaxant effects on smooth muscle strips from aorta and renal and inferior mesenteric arteries. The isolation procedure included several steps of gel-permeation and ion-exchange chromatography, and high performance liquid chromatography. During the isolation procedure, other peptides of smaller molecular weight were also found, which, in relation to cardiodilatin-126 (CDD-126), are shorter at their N-terminal. Among these, CDD-88 has also been isolated and characterizied, and has been established as a prominent member of the cardiac hormone family. The N-terminal and C-terminal segments of the 126 amino acid-containing molecule were synthesized and used to raise region-specific antibodies. The natural peptide was then localized within myoendocrine cells of the right atrium where specific atrial granules are located. Renal effects of cardiodilation were studied in conscious dogs and showed strong diuretic and natriuretic activities. According to our functional studies, cardiodilatin-126 and cardiodilatin-88 possess qualities of a significant hormone family regarding the regulation of extracellular fluid volume and blood pressure.

    Notes: Summary An immunohistochemical study of glucagon and glicentin immunoreactive endocrine cells in the human colon epithelium was performed. Serial sections and qualitative analysis show a cell population containing both immunoreactivities. However, there is another cell population exhibiting only an immunoreactivity with glicentin. The exact distribution of these immunoreactive endocrine cells within the colon crypt segments is also analysed. The significance of these findings concerning the synthesis of glucagon and glicentin and their function is discussed.

    Evidence that myosin light chain phosphorylation regulates contraction in the body wall muscles of the sea cucumber (1982)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The Ca2+ activation mechanism of the longitudinal body wall muscles of Parastichopus californicus (sea cucumber) was studied using skinned muscle fiber bundles. Reversible phosphorylation of the myosin light chains correlated with Ca2+-activated tension and relaxation. Pretreatment of the skinned fibers with ATPγS and high Ca2+ (10-5M) resulted in irreversible thiophosphorylation of the myosin light chains and activation of a Ca2+ insensitive tension. In contrast, pretreatment with low Ca2+ (10-8M) and ATPγS results in no thiophosphorylation of the myosin light chains or irreversible activation of tension. These results are consistent with a Ca2+-sensitive myosin light chain kinase/phosphatase system being responsible for the activation of the muscle. Other agents known to have an effect upon the Ca2+-activated tension in skinned vertebrate smooth muscle fibers (trifluoperazine, catalytic subunit of the cyclic AMP-dependent protein kinase, and calmodulin) did not have an effect on myosin light chain phosphorylation or Ca2+-activated tension. These results suggest a different type of myosin light chain kinase than is found in vertebrate smooth muscle is responsible for the activation of parastichopus longitudinal body wall muscle.

    Notes: This scanning and transmission electron microscopical study has been performed to determine the extent of the development of the subacrosomal space in the sperm head of various members of the subfamily, the Hydromyinae, which is a diverse group of murid rodents occurring in various habitats in Australia. Sperm of all species from the three tribes of Hydromyini, Uromyini, and Conilurini investigated in this study had a head with three hooks although their absolute and relative lengths varied markedly. The top hook was similar in structure to that present in many other murid rodents and had a typical pseudoperforatorium present. The two ventral hooks had nuclear material basally, apical to which a large extension of the subacrosomal space occurred. Studies of testicular sections showed that the ventral hooks were formed late in spermiogenesis largely after condensation of the nucleus during which time electron dense material accumulated within them. No structure homologous to these hooks has been found in sperm from any other mammalian group, but, as the three tribes of Hydromyinae probably diverged about 20 million years ago, the extension of the subacrosomal space presumably evolved prior to this date.

    Structure of the vesicular stomatitis virus nucleoprotein-RNA complex (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-06-17
    Description: Vesicular stomatitis virus is a negative-stranded RNA virus. Its nucleoprotein (N) binds the viral genomic RNA and is involved in multiple functions including transcription, replication, and assembly. We have determined a 2.9 angstrom structure of a complex containing 10 molecules of the N protein and 90 bases of RNA. The RNA is tightly sequestered in a cavity at the interface between two lobes of the N protein. This serves to protect the RNA in the absence of polynucleotide synthesis. For the RNA to be accessed, some conformational change in the N protein should be necessary.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, Todd J -- Zhang, Xin -- Wertz, Gail W -- Luo, Ming -- AI050066/AI/NIAID NIH HHS/ -- R37 AI012464/AI/NIAID NIH HHS/ -- R37 AI012464-28/AI/NIAID NIH HHS/ -- R37 AI012464-29/AI/NIAID NIH HHS/ -- R37 AI012464-30/AI/NIAID NIH HHS/ -- R37 AI012464-31/AI/NIAID NIH HHS/ -- R37AI012464/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2006 Jul 21;313(5785):357-60.

    The schizophrenia susceptibility gene dysbindin controls synaptic homeostasis (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-12-08
    Description: The molecular mechanisms that achieve homeostatic stabilization of neural function remain largely unknown. To better understand how neural function is stabilized during development and throughout life, we used an electrophysiology-based forward genetic screen and assessed the function of more than 250 neuronally expressed genes for a role in the homeostatic modulation of synaptic transmission in Drosophila. This screen ruled out the involvement of numerous synaptic proteins and identified a critical function for dysbindin, a gene linked to schizophrenia in humans. We found that dysbindin is required presynaptically for the retrograde, homeostatic modulation of neurotransmission, and functions in a dose-dependent manner downstream or independently of calcium influx. Thus, dysbindin is essential for adaptive neural plasticity and may link altered homeostatic signaling with a complex neurological disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3063306/" 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/PMC3063306/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dickman, Dion K -- Davis, Graeme W -- NS39313/NS/NINDS NIH HHS/ -- R01 NS039313/NS/NINDS NIH HHS/ -- R01 NS039313-12/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1127-30. doi: 10.1126/science.1179685.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Biophysics, University of California, San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965435" target="_blank"〉PubMed〈/a〉

    Cerebellar afferents to paramedian lobule from the trigeminal complex in Tupaia glis: A horseradish peroxidase (HRP) study (1982)

    Notes: Projections from the trigeminal complex to paramedian lobule (PML) were studied in the tree shrew (Tupaia glis) by means of retrograde transport of horseradish peroxidase (HRP). Neurons which project to both dorsal and ventral folia of PML are located primarily in those areas of the trigeminal nuclear complex interpreted as nucleus interpolaris (Vi) and caudal areas of the nucleus oralis (Vo). The majority of HRP-labeled neurons lie in ventral and ventrolateral regions of Vi/Vo. No HRP-reactive cells are present in the principal (Vp), mesencephalic, or motor nuclei nor in nucleus caudalis or rostral portions of oralis. The majority of trigeminocerebellar (TC) cells are found in ipsilateral Vi; however, sparse numbers of labeled somata are present in this subnucleus on the contralateral side. Within Vi/Vo, small fusiform and medium- and large-sized multipolar neurons contain HRP-reaction product. Large multipolar cells are found primarily in ventrolateral portions of Vi/Vo, while medium and small neurons are scattered throughout the ventral half of the nucleus. Small-sized neurons are also present dorsally within Vi/Vo. Axons of labeled TC cells course laterally through the spinal trigeminal tract, enter medial aspects of the restiform body, and arch dorsally into the cerebellum.

    A basement membrane-associated glycoprotein from skeletal muscle (1982)

    Notes: We have isolated a major glycoprotein that appears to be associated with rat skeletal muscle basement membrane. We determined that the glycoprotein was part of the muscle cell surface complex when we found it to be enriched in preparations of muscle ghosts. We isolate the glycoprotein from homogenized muscle preextracted with 4 M and 8 M urea. It elutes as a major component in the presence of 8 M urea/50 mM 2-mercaptoethanol. Its apparent molecular weight on sodium dodecyl sulfate gels is 130,000. Amino acid analysis indicates that it is not a collagen but that it does contain small amounts of hydroxyproline and hydroxylysine. There may be collagenous domains in the glycoprotein molecule, for it is cleaved into three fragments by purified bacterial collagenase. Immunoperoxidase staining confirms that the 130,000-dalton protein is localized at the surface of adult skeletal muscle cells. It is probably a general basement membrane-associated glycoprotein because we found material immunologically cross-reactive with the muscle glycoprotein in basement membrane regions of kidney, liver, brain, and small intestine. We have shown the glycoprotein to be distinct from fibronectin, laminin, and types I, III, IV, and V collagens in enzyme-linked immunosorbent assays.
