Syntaxin is required for cell division.
We recently identified a single family member homologue of syntaxin in the sea urchin. Syntaxin is present throughout development, and in rapidly dividing cleavage stage embryos it is present on numerous vesicles at the cell cortex. We hypothesized that syntaxin mediates essential membrane fusion events during early embryogenesis, reasoning that the vesicles and/or their contents are important ...
متن کاملPlatelet secretion and hemostasis require syntaxin-binding protein STXBP5.
Genome-wide association studies (GWAS) have linked genes encoding several soluble NSF attachment protein receptor (SNARE) regulators to cardiovascular disease risk factors. Because these regulatory proteins may directly affect platelet secretion, we used SNARE-containing complexes to affinity purify potential regulators from human platelet extracts. Syntaxin-binding protein 5 (STXBP5; also know...
متن کاملMunc18‐2 is required for Syntaxin 11 Localization on the Plasma Membrane in Cytotoxic T‐Lymphocytes
Cytotoxic T-lymphocytes (CTL) kill their targets by cytolytic granule secretion at the immunological synapse. The Sec/Munc protein, Munc18-2, and its binding partner Syntaxin 11 (STX11) are both required for granule secretion, with mutations in either leading to the primary immunodeficiency, Familial Haemophagocytic Lymphohistiocytosis (FHL4 and 5). Understanding how Munc18-2 and STX11 function...
متن کاملCutting edge: syntaxin 11 regulates lymphocyte-mediated secretion and cytotoxicity.
Little is known about the regulatory roles of specific soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins in cytotoxic lymphocytes. Recent information suggests that mutations in the SNARE protein syntaxin 11 result in a form of familial hemophagocytic lymphohistiocytosis (FHL). Because genetic abnormalities in key granule components (e.g., perforin) or in reg...
متن کاملUNC-13 Interaction with Syntaxin Is Required for Synaptic Transmission
Neurotransmitter secretion at synapses is controlled by several processes-morphological docking of vesicles at release sites, priming of docked vesicles to make them fusion competent, and calcium-dependent fusion of vesicles with the plasma membrane . In worms, flies, and mice, mutants lacking UNC-13 have defects in vesicle priming . Current models propose that UNC-13 primes vesicles by stabili...
