Summaries for SNAP25 Gene

Entrez Gene Summary for SNAP25 Gene

  • Synaptic vesicle membrane docking and fusion is mediated by SNAREs (soluble N-ethylmaleimide-sensitive factor attachment protein receptors) located on the vesicle membrane (v-SNAREs) and the target membrane (t-SNAREs). The assembled v-SNARE/t-SNARE complex consists of a bundle of four helices, one of which is supplied by v-SNARE and the other three by t-SNARE. For t-SNAREs on the plasma membrane, the protein syntaxin supplies one helix and the protein encoded by this gene contributes the other two. Therefore, this gene product is a presynaptic plasma membrane protein involved in the regulation of neurotransmitter release. Two alternative transcript variants encoding different protein isoforms have been described for this gene. [provided by RefSeq, Jul 2008]

GeneCards Summary for SNAP25 Gene

SNAP25 (Synaptosome Associated Protein 25kDa) is a Protein Coding gene. Diseases associated with SNAP25 include Myasthenic Syndrome, Congenital, 18 and Presynaptic Congenital Myasthenic Syndromes. Among its related pathways are Uptake and actions of bacterial toxins and Synaptic vesicle cycle. GO annotations related to this gene include calcium-dependent protein binding and SNAP receptor activity. An important paralog of this gene is SNAP23.

UniProtKB/Swiss-Prot for SNAP25 Gene

  • t-SNARE involved in the molecular regulation of neurotransmitter release. May play an important role in the synaptic function of specific neuronal systems. Associates with proteins involved in vesicle docking and membrane fusion. Regulates plasma membrane recycling through its interaction with CENPF. Modulates the gating characteristics of the delayed rectifier voltage-dependent potassium channel KCNB1 in pancreatic beta cells.

    Quaternary structure:
    • Part of the SNARE core complex containing SNAP25, VAMP2 and STX1A. This complex binds CPLX1. Interacts with CENPF, TRIM9, RIMS1, SNAPIN, OTOF and HGS. Binds STXBP6. Found in a ternary complex with STX1A and VAMP8. Found in a complex containing SYT1, SV2B and syntaxin-1 (By similarity). Associates with the BLOC-1 complex. Isoform 1 and isoform 2 interact with BLOC1S6. Interacts with EQTN. Interacts with KCNB1 (via N-terminus); reduces the voltage-dependent potassium channel KCNB1 activity in pancreatic beta cell. Interacts with ZDHHC13 (via ANK repeats). Interacts with ZDHHC17 (via ANK repeats) (By similarity).
    • When cloned and expressed in Eschericia coli, where protein palmitoylation does not occur, Cys-85, Cys-88, Cys-90 and Cys-92 in the protein sequence readily form an iron-sulfur cluster instead.

Clinical features are easy fatigability and muscle weakness affecting the axial and limb muscles (with hypotonia in early-onset forms), the ocular muscles (leading to ptosis and ophthalmoplegia), and the facial and bulbar musculature (affecting sucking and swallowing, and leading to dysphonia). The symptoms fluctuate and worsen with physical effort. CMS18 is an autosomal dominant presynaptic disorder clinically characterized by early-onset muscle weakness and easy fatigability associated with delayed psychomotor development and ataxia. {ECO:0000269 PubMed:25381298}.
