Anti-CDC42EP3 antibodies are used in the immunodetection of the protein CDC42 effector protein 3. In humans, the canonical protein has a reported length of 254 amino acid residues and a mass of 27.7 kDa. Its subcellular localization is in the membrane and cytoplasm. It is reported to be highly expressed in the heart and weakly in the brain. A member of the BORG/CEP protein family, CDC42EP3 is suspected to be involved in the organization of the actin cytoskeleton. Synonyms for this target antigen include CEP3, UB1, CDC42 effector protein (Rho GTPase binding) 3, CRIB-containing BORG2 protein, MSE55-related Cdc42-binding protein, and BORG2. CDC42EP3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CDC42EP3 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
