SPINK13 (Serine Peptidase Inhibitor Kazal type 13).

This basic part encodes Human serine protease inhibitor known as SPINK13 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 predicted to be able to inhibit serine peptidases. The inhibitor is present extracellularly and is predicted to be involved in the feedback inhibition of acivation of premature acrosomal reaction sperms. The inhibitor binds to trypsin proteases and since the catalytic core of HtrA1 (BBa_K4165004) is considered as a tyrpsin-like catalytic domain, so this inhibitor also is considered to inhibit the function of HtrA1 [1] - [4].
