Rab3A Antibody

Ras-related protein Rab-3A is a protein that in humans is encoded by the RAB3A gene. Synapsin I stimulated the Rab3A cycle by increasing GTP binding, GTPase activity, and Rab3A recruitment to the synaptic vesicle membrane. Conversely, Rab3A inhibited Synapsin I binding to actin and Synapsin I-induced synaptic vesicle clustering. It has been found that the protein is necessary for both forms of synaptic plasticity, and it is also involved in calcium exocytosis in neurons. In addition to that, Rab3A has been found to regulate a late step in synaptic vesicle fusion.
