STXBP1 (Syntaxin-binding protein 1; also p67, Munc18-1, N-Sec1 and Unc18A) is a 67kD member of the SNARE-interacting Sec1/Unc18/STXBP family of proteins. It is expressed in a variety of cells, presumably in those that exhibit granule exocytosis, and likely participates in (synaptic) granule release. Ligands for STXBP1 include STX1A, 2 and 3, and it is possible that STXBP1 both suppresses STX activity, and serves as an anchor for STX-mediated vesicle fusion. Human STXBP1 is 594aa in length. It contains one SEC1 domain (aa41-575). Phosphorylation at Ser313 may stimulate granule release. There is one splice variant that shows a 28aa substitution for aa576-594. This is restricted to neural tissue. Over aa80-226, human and mouse STXBP1 are absolutely identical in amino acid sequence.
