Anti-RAC3 antibodies are used in the immunodetection of the protein Rac family small GTPase 3. In humans, the canonical protein has a reported length of 192 amino acid residues and a mass of 21.4 kDa. Its subcellular localization is in the cell membrane and cytoplasm. It is reported to be highly expressed in the brain, also detected in the heart, placenta and pancreas. A member of the Rho protein family, RAC3 is known to be involved with cytoskeleton organization and the apoptotic pathway. Synonyms for this target antigen include p21-Rac3, ras-related C3 botulinum toxin substrate 3 (rho family, small GTP binding protein Rac3), rho family, small GTP binding protein Rac3, and ras-related C3 botulinum toxin substrate 3. RAC3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 160 citations in the literature describe the use of rac3 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
