Mouse Anti-SYT4 Recombinant Antibody (CBXS-5061) (CBMAB-S2282-CQ)

synaptotagmin IV

SYT4 (Synaptotagmin 4) is a Protein Coding gene. Gene Ontology (GO) annotations related to this gene include calcium ion binding and syntaxin binding. An important paralog of this gene is SYT11.May be involved in Ca(2+)-dependent exocytosis of secretory vesicles through Ca(2+) and phospholipid binding to the C2 domain or may serve as Ca(2+) sensors in the process of vesicular trafficking and exocytosis (By similarity). Plays a role in dendrite formation by melanocytes (PubMed:23999003).

HsT1192

Synaptotagmin family member which does not bind Ca2+ (PubMed:23999003) (By similarity).
Involved in neuronal dense core vesicles (DCVs) mobility through its interaction with KIF1A. Upon increased neuronal activity, phosphorylation by MAPK8/JNK1 destabilizes the interaction with KIF1A and captures DCVs to synapses (By similarity).
Plays a role in dendrite formation by melanocytes (PubMed:23999003).
