Anti-APOBEC2 antibodies are used in the immunodetection of the protein apolipoprotein B mRNA editing enzyme catalytic subunit 2. In humans, the canonical protein has a reported length of 224 amino acid residues and a mass of 25.7 kDa. It is found to be preferentially expressed in the heart and skeletal muscle. A member of the Cytidine and deoxycytidylate deaminase protein family, APOBEC2 is a suspected C to U editing enzyme whose physiological substrate is not yet known. Synonyms for this target antigen include ARP1, apolipoprotein B mRNA editing enzyme, catalytic polypeptide 2, apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like 2, and ARCD1. APOBEC2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of APOBEC2 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.
