Anti-ALT1 antibodies are protein reagents that detect specific antigens. The ALT1 antigen is another term for the human protein glutamic--pyruvic transaminase, encoded by the GPT gene. The protein is known to catalyze the reversible transamination between alanine and 2-oxoglutarate to form pyruvate and glutamate. Canonically, it has an amino acid length of 496 residues and a mass of 54.6 kilodaltons. Its subcellular localization is in the cytoplasm and it is expressed in many tissues, such as the colon and gallbladder. The ALT1 protein is a member of the Class-I pyridoxal-phosphate-dependent aminotransferase protein family. Other alias names for ALT1 include AAT1 and ALT. Western Blot is the most common application for the ALT1 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
