[[http://www.uniprot.org/uniprot/SYT1_RAT SYT1_RAT]] May have a regulatory role in the membrane interactions during trafficking of synaptic vesicles at the active zone of the synapse. It binds acidic phospholipids with a specificity that requires the presence of both an acidic head group and a diacyl backbone. A Ca(2+)-dependent interaction between synaptotagmin and putative receptors for activated protein kinase C has also been reported. It can bind to at least three additional proteins in a Ca(2+)-independent manner; these are neurexins, syntaxin and AP2. [[http://www.uniprot.org/uniprot/SNP25_RAT SNP25_RAT]] 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. [[http://www.uniprot.org/uniprot/VAMP2_RAT VAMP2_RAT]] Involved in the targeting and/or fusion of transport vesicles to their target membrane (By similarity). [[http://www.uniprot.org/uniprot/STX1A_RAT STX1A_RAT]] Potentially involved in docking of synaptic vesicles at presynaptic active zones. May play a critical role in neurotransmitter exocytosis. May mediate Ca(2+)-regulation of exocytosis acrosomal reaction in sperm. [[http://www.uniprot.org/uniprot/CPLX1_RAT CPLX1_RAT]] Positively regulates a late step in synaptic vesicle exocytosis. Organizes the SNAREs into a cross-linked zigzag topology that, when interposed between the vesicle and plasma membranes, is incompatible with fusion, thereby preventing SNAREs from releasing neurotransmitters until an action potential arrives at the synapse. Also involved in glucose-induced secretion of insulin by pancreatic beta-cells (By similarity).
