SPINK1 (Serine Peptidase Inhibitor Kazal type 1).

This basic part encodes Human serine protease inhibitor known as SPINK1 which is able to inhibit trypsin-like proteases, like HtrA1 (BBa_K4165004).


Usage and Biology

This type of family encodes for a type of inhibitor that is able to inhibit trypsins. The inhibitor is secreted from pancreatic acinar cells into the pancreatic juice. The main function of the inhibitor in pancreatic juice is the prevention of activation of immature trypsin zymogens within the pancreatic duct. The inhibitor binds to trypsin proteases and since the catalytic core of HtrA1 (BBa_K4165004) is considered as a trypsin-like catalytic domain, so this inhibitor also is considered to inhibit the function of HtrA1.
