Anti-ACTR1A antibodies are used in the immunodetection of the protein actin related protein 1A. In humans, the canonical protein has a reported length of 376 amino acid residues and a mass of 42.6 kDa. Its subcellular localization is in the cytoplasm. It is notably widely expressed in many tissue types. A member of the Actin protein family, ACTR1A is known to be a part of the ACTR1A/ACTB filament around which the dynactin complex is built. Synonyms for this target antigen include Arp1A, CTRN1, alpha-centractin, ARP1 actin related protein 1 homolog A, ARP1 actin-related protein 1 homolog A, centractin alpha, and ARP1. ACTR1A gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some ACTR1A antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
