Human Synaptotagmin 4,SYT4 ELI

Synaptotagmin family member which does not bind Ca(2+) (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).
