Background Information

GPT2 (Alanine aminotransferase 2; ALT2) is a key enzyme in intermediatary metabolism, catalysing the reversible transfer of the amino group of glutamate to pyruvate, yielding alanine and ketoglutarate. GPT2 protein localizes to mitochondria, and is mainly expressed in the pancreas, brain, adrenal gland, skeletal muscle and heart. Serum GPT2 is a useful marker for liver damage. Recently mutation of GPT2 has been reported to be a cause of neural disorder (27601654). 16757-1-AP antibody recognizes two different isoforms of GPT2 protein.
