Anti-ANKRD2 antibodies are used in the immunodetection of the protein ankyrin repeat domain 2. In humans, the canonical protein has a reported length of 360 amino acid residues and a mass of 39.9 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably expressed in skeletal and cardiac muscles. ANKRD2 is known to function as a negative regulator of myocyte differentiation. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include ankyrin repeat domain-containing protein 2, ankyrin repeat domain 2 (stretch responsive muscle), skeletal muscle ankyrin repeat protein, and ARPP. ANKRD2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of ANKRD2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
