SPINK9 (Serine Peptidase Inhibitor Kazal type 9).

This basic part encodes Human serine protease inhibitor known as SPINK9 which is able to inhibit trypsin-like proteases, like HtrA1 (BBa_K4165004).


Usage and Biology

This part encodes for a type of inhibitor that is able to inhibit serine proteases and it is predicted to be located extracellularly. The main function of the inhibitor is to specifically target kallikrein-related peptide 5 (KLK-5) which is an important initiator of skin peeling. 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 [1] - [4].
