Primary antibody说明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.
功能Involved in exocytosis by regulating a late step in synaptic vesicle fusion. Could play a role in neurotransmitter release by regulating membrane flow in the nerve terminal.
组织特异性Specifically expressed in brain.
序列相似性Belongs to the small GTPase superfamily. Rab family.

Immunofluorescence analysis of RAB3A was done on 70% confluent log phase HeLa (Human epithelial adenocarcinoma cell line)
cells. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.1% Triton™ X-100 for 10 minutes, and blocked with 1% BSA for 1 hour at room temperature. The cells were labeled with ab3335 at 2 µg/mL in 0.1% BSA and incubated for 3 hours at room temperature and then labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate at 1/2000 dilution for 45 minutes at room temperature (Panel a: green). Nuclei (Panel b: blue) were stained with SlowFade® Gold Antifade Mountant with DAPI. F-actin (Panel c: red) was stained with Alexa Fluor® 555 Rhodamine Phalloidin at 1/300 dilution. Panel d is a merged image showing Cytoplasmic localization. Panel e is a no primary antibody control. The images were captured at 60X magnification.
