Anti-NUDT2 antibodies are used in the immunodetection of the protein nudix hydrolase 2. In humans, the canonical protein has a reported length of 147 amino acid residues and a mass of 16.8 kDa. A member of a the Nudix hydrolase protein family, NUDT2 is known to catalyze the asymmetric hydrolysis of diadenosine 5',5'''-P1,P4-tetraphosphate (Ap4A) to yield AMP and ATP (By similarity). Synonyms for this target antigen include IDDPN, bis(5'-nucleosyl)-tetraphosphatase [asymmetrical], Ap4A hydrolase 1, Ap4Aase, and APAH1.
