Alpha-1 antitrypsin or α 1-antitrypsin (A1AT, α 1 AT, A1A, or AAT) is a protein belonging to the serpin superfamily. It is encoded in humans by the SERPINA1 gene . A protease inhibitor , it is also known as alpha 1 –proteinase inhibitor ( A1PI ) or alpha 1 -antiproteinase ( A1AP ) because it inhibits various proteases (not just trypsin ). [ 5 ]
