Summary: This gene encodes a member of the syntaxin superfamily. Syntaxins are nervous system-specific proteins implicated in the docking of synaptic vesicles with the presynaptic plasma membrane. Syntaxins possess a single C-terminal transmembrane domain, a SNARE [Soluble NSF (N-ethylmaleimide-sensitive fusion protein)-Attachment protein REceptor] domain (known as H3), and an N-terminal regulatory domain (Habc). Syntaxins bind synaptotagmin in a calcium-dependent fashion and interact with voltage dependent calcium and potassium channels via the C-terminal H3 domain. This gene product is a key molecule in ion channel regulation and synaptic exocytosis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]
Expression: Biased expression in brain (RPKM 28.2), bone marrow (RPKM 2.7) and 3 other tissues See more

Syntaxin 1: A Novel Robust Immunophenotypic Marker of Neuroendocrine Tumors.
Title: Syntaxin 1: A Novel Robust Immunophenotypic Marker of Neuroendocrine Tumors.
The N-terminal of the SNAP25 loop region binds with membrane, and this interaction induced a disorder-to-order conformational change of the loop, resulting in enhanced interaction between the C-terminal of the SNAP25 loop and syx-1. SNARE-complex assembly efficiency decreased when the electrostatic interaction between C-terminal of the SNAP25 loop and syx-1 was disrupted.

Using a case-control study to explore the association between STX1A gene and children with ADHD in Chinese Han population, our results suggest STX1A genetic variants might contribute to the susceptibility of children ADHD.

Results suggest a role of Stx-1A rs4717806 SNP in ischemic heart disease, possibly due to its influence in Stx-1A expression and, at cascade, to insulin secretion and to glucose dependent metabolism.

Analysing protein mobility, cluster size and accessibility to myc-epitopes the authors show that forces acting on the transmembrane segment produce loose clusters, while cytoplasmic protein interactions mediate a tightly packed state.
Title: The packing density of a supramolecular membrane protein cluster is controlled by cytoplasmic interactions.
Our results suggest that, as in the CNS, CADM1 interactions drive exocytic site assembly and promote actin network formation. These results support the broader hypothesis that the effects of cell-cell contact on beta-cell maturation and function are mediated by the same extracellular protein interactions that drive the formation of the presynaptic exocytic machinery. These interactions may be therapeutic targets for re...

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
