Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables several functions, including calcium ion sensor activity; calcium-dependent phospholipid binding activity; and syntaxin-1 binding activity. Involved in modulation of chemical synaptic transmission; regulation of dopamine secretion; and synaptic vesicle exocytosis. Acts upstream of or within calcium ion-regulated exocytosis of neurotransmitter; spontaneous neurotransmitter secretion; and synchronous neurotransmitter secretion. Located in several cellular components, including Golgi apparatus; presynaptic membrane; and secretory vesicle. Is active in glutamatergic synapse. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; peripheral nervous system ganglion; and sensory organ. Orthologous to human SYT1 (synaptotagmin 1).
