General description

Synaptotagmin-4 (UniProt Q9H2B2; also known as Synaptotagmin IV, SytIV) is encoded by the SYT4 (also known as KIAA1342) gene (Gene ID 6860) in human. The mammalian synaptotagmin family is comprised of 17 members. While most of them are predominantly function in the cetnral nervous system (CNS), some are involved in the vesicular functions of endocrine cells and glucose-transport metabolic cells. Synaptotagmin-4 is an inducible member detectable only in the brain and the neuroendocrine system. Unlike other family members, synaptotagmin-4 does not bind calcium and does not medidate calcium-induced exocytosis. Instead, synaptotagmin-4 is shown to play a neuroendocrine role in inhibiting exocytotic activities in the posterior pituitary and in cultured PC12 cells. Synaptotagmin-4 is expressed most abundantly in oxytocin neurons of the hypothalamus, where it negatively regulates oxytocin exocytosis. Dietary obesity is associated with increased vesicle binding of synaptotagmin-4 and decreased oxytocin release. Normalizing oxytocin release via Synaptotagmin-4 inhibition prevents against dietary obesity under chronic nutritional excess. Human synaptotagmin-4 consists of a vesiclular domain (a.a. 1-16), a transmembrane segment (a.a. 17-37),and a large cytoplasmic domain (a.a. 38-425).
