SPINK6 (Serine Peptidase Inhibitor Kazal type 6).

This basic part encodes Human serine protease inhibitor known as SPINK6 which is able to inhibit serine peptidases.


Usage and Biology

This type of family encodes for a type of inhibitor that is able to inhibit serine peptidases, especially kallkreins. The inhibitor’s main function is to inhibit kallikrein-related peptidases in the skin. The inhibitor binds to serine peptidases and since the catalytic core of HtrA1 (BBa_K4165004) is considered as a serine catalytic domain, so this inhibitor also is considered to inhibit the function of HtrA1 [1-3].
