WAP-four disulfide core domain 14 serine protease inhibitor.

This basic part encodes Human serine protease inhibitor WAP-four disulfide core domain 14 which is able to inhibit HtrA1 (BBa_K4165004).


Usage and Biology

This type of family encodes for a type of inhibitor that contains a motif which consists of 8 cysteine residues capable of forming four disulfide bonds at the core of the protease, thus inhibiting its action. The main function of this inhibitor is to prevent elastase-mediated tissue proteolysis. This type of inhibitor is very effective and has high affinity for trypsin-like proteases (serine proteases), and in our case it would act as an inhibitor for the trypsin-like catalytic domain of serine protease HtrA1[1]-[3].
