IgG purified |
| Dilution Range: |
IHC, WB. Use at a dilution of 1:4000 to 1: 5000. The optimal dilution should be determined by the end user. Not yet tested in other applications. |
| Storage Instruction: |
Maintain the lyophilised/reconstituted antibodies frozen at-20°C for long term storage and refrigerated at 2-8°C for a shorter term. When reconstituting, Glycerol (1:1) may be added for an additional stability. Avoid freeze and thaw cycles. |
| Gene Symbol: |
RAB3A |
| Gene ID: |
5864 |
| Uniprot ID: |
RAB3A_HUMAN |
| Immunogen Region: |
2-50 aa |
| Specificity: |
Specific for RAB3. |
| Immunogen: |
A synthetic peptide from aa region 2-50 of mouse RAB3A conjugated to blue carrier protein has been used as the antigen. The antigen is homologous for RAB3B, C, D in human and rat. |
| Post Translational Modifications | Phosphorylation of Thr-86 in the switch II region by LRRK2 prevents the association of RAB regulatory proteins, including CHM, CHML and RAB GDP dissociation inhibitors GDI1 and GDI2. |
| Function | Small GTP-binding protein that plays a central role in regulated exocytosis and secretion. Controls the recruitment, tethering and docking of secretory vesicles to the plasma membrane. Upon stimulation, switches to its active GTP-bound form, cycles to vesicles and recruits effectors such as RIMS1, RIMS2, Rabphilin-3A/RPH3A, RPH3AL or SYTL4 to help the docking of vesicules onto the plasma membrane. Upon GTP hydrolysis by GTPase-activating protein, dissociates from the vesicle membrane allowing the exocytosis to proceed. Stimulates insulin secretion through interaction with RIMS2 or RPH3AL effectors in pancreatic beta cells. Regulates calcium-dependent lysosome exocytosis and plasma membrane repair (PMR) via the interaction with 2 effectors, SYTL4 and myosin-9/MYH9. Acts as a positive regulator of acrosome content secretion in sperm cells by interacting with RIMS1. Also plays a role in the regulation of dopamine release by interacting with synaptotagmin I/SYT. Interacts with MADD (via uDENN domain).the GTP-bound form is preferred for interaction. |
