SERPINA1

Universal Cellular Machinery · Proteolysis & Protease Inhibition

Why does the body need alpha-1 antitrypsin to control other enzymes?

SERPINA1 makes alpha-1 antitrypsin, an inhibitor that restrains protein-digesting enzymes. This protection helps prevent normal enzyme activity from damaging tissues, particularly in the lungs.
