靶點詳情

功能:Participates in the regulation of synaptic vesicle docking and fusion through interaction with GTP-binding proteins. Essential for neurotransmission and binds syntaxin, a component of the synaptic vesicle fusion machinery probably in a 1:1 ratio. Can interact with syntaxins 1, 2, and 3 but not syntaxin 4. May play a role in determining the specificity of intracellular fusion reactions.

- This analysis provides strong evidence of DNA motif modulated mutagenesis for STXBP1 de novo splicing mutations. PMID: 29438995
- Glucose-dependent de-SUMOylation of tomosyn1 at K298 releases syntaxin1A and controls the amplification of exocytosis in concert with a recently-identified tomosyn1-interacting partner; the Ca(2+)-binding protein secretagogin, which dissociates from tomosyn1 in response to Ca(2+)-raising stimuli and is required for insulin granule trafficking and exocytosis downstream of Ca(2+) influx.
