Anti-CAPZA1 antibodies are used in the immunodetection of the protein capping actin protein of muscle Z-line subunit alpha 1. In humans, the canonical protein has a reported length of 286 amino acid residues and a mass of 32.9 kDa. Its subcellular localization is in the cytoplasm. It is notably widely expressed in many tissue types. A member of the F-actin-capping protein alpha subunit protein family, CAPZA1 is known to be involved with cytoskeleton organization and the assembly of protein complexes. Synonyms for this target antigen include CAPZ, CAZ1, F-actin-capping protein subunit alpha-1, Cap Z, capZ alpha-1, and CAPPA1. CAPZA1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of CAPZA1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
