human brain tissue were subjected to SDS PAGE followed by western blot with FNab07032(RAB3IL1 antibody) at dilution of 1:500
Background
Guanine nucleotide exchange factor(GEF) which may activate RAB3A, a GTPase that regulates synaptic vesicle exocytosis. Promotes the exchange of GDP to GTP, converting inactive GDP-bound Rab proteins into their active GTP-bound form. May also activate RAB8A and RAB8B.
