SPINK2 (Serine Peptidase Inhibitor Kazal type 2).

This basic part encodes Human serine protease inhibitor known as SPINK2 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 main function of the inhibitor is hindering the premature activation of proacrosin and many other proteases, thus preventing defects in the spermiogenesis process. 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] - [3].
