Anti-ACTR2 antibodies are used in the immunodetection of the protein actin related protein 2. In humans, the canonical protein has a reported length of 394 amino acid residues and a mass of 44.8 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Actin protein family, ACTR2 is reported to be an atp-binding 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 ARP2 actin related protein 2 homolog, actin-like protein 2, and ARP2. ACTR2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 70 citations in the literature describe the use of ACTR2 antibodies in research. Western Blot, Immunofluorescence, and Immunohistochemistry are common applications for these antibodies.
