RAB3GAP1 Antibody Blocking Peptide

Probable catalytic subunit of a GTPase activating protein that has specificity for Rab3 subfamily (RAB3A， RAB3B， RAB3C and RAB3D). Rab3 proteins are involved in regulated exocytosis of neurotransmitters and hormones. Specifically converts active Rab3-GTP to the inactive form Rab3-GDP. Required for normal eye and brain development. May participate in neurodevelopmental processes such as proliferation， migration and differentiation before synapse formation， and non-synaptic vesicular release of neurotransmitters.
