Anti-ALASE antibodies enable researchers to detect and measure the ALASE antigen in biological samples. This target is a reported synonym of the ALAS2 gene, which encodes 5'-aminolevulinate synthase 2. This protein is known to function in erythrocyte differentiation, among other biological roles. The human version of ALASE has a canonical amino acid length of 587 residues and a protein mass of 64.6 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the mitochondria of cells. ALASE is a member of the Class-II pyridoxal-phosphate-dependent aminotransferase protein family.
