Anti-ARPC3 antibodies are used in the immunodetection of the protein actin related protein 2/3 complex subunit 3. In humans, the canonical protein has a reported length of 178 amino acid residues and a mass of 20.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably widely expressed in many tissue types. A member of the ARPC3 protein family, ARPC3 is a known component of the Arp2/3 complex, a multiprotein complex that mediates actin polymerization upon stimulation by nucleation-promoting factor (NPF). Synonyms for this target antigen include p21-Arc, actin-related protein 2/3 complex subunit 3, ARP2/3 protein complex subunit p21, actin related protein 2/3 complex, subunit 3, 21kDa, arp2/3 complex 21 kDa subunit, and ARC21. ARPC3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of ARPC3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
