Enterokinase, also known as Serine protease 7 and Enteropeptidase, is a 113kDa 1019 amino acid protein and can be found in the membrane. The primary function of Enterokinase is to encode an enzyme wich converts the pancreatic proenzyme trypsinogen to trypsin. Current research is being conducted on Enterokinase in relation to breast cancer, fibrosacroma, influenza, steatorrhea, hymenolepiasis and pancreatitis. Enterokinase interacts with SPINK1.
