Rab3A Antibody

Rab proteins are low-molecular-weight GTP-binding proteins that form the largest branch of the Ras superfamily of GTPases. Located on the cytoplasmic face of organelles and vesicles, rab proteins are involved in intracellular membrane fusion reactions. Three membrane proteins, synaptosomal associated protein of 25 kDa (SNAP-25), synaptobrevin and syntaxin, form the core of a ubiquitous membrane fusion machine that interacts with the soluble proteins N-ethylmaleimide-sensitive factor (NSF) and a-SNAP. Rab proteins, in co-ordination with the core fusion machinery and Munc-18, help to mediate vesicle docking and fusion. There exist over 40 rab proteins that have been described in mammals and the best studied is rab 3A. Rab 3A is found to be abundant in presynaptic nerve terminals and is also found to be crucial in acrosomal exocytosis in human spermatozoa. Abnormal accumulation of rab 3A in the cytoplasm of Purkinje cells has been reported in the prion protein related Creutzfeldt-Jakob disease.
