SPINK14 (Serine Peptidase Inhibitor Kazal type 14).

This basic part encodes Human serine protease inhibitor known as SPINK14 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 predicted to be able to inhibit serine peptidases. The inhibitor is present extracellularly. The inhibitor binds to trypsin-like proteases (serine 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 [1-3].
