WAP-four disulfide core domain 13 serine protease inhibitor.
This basic part encodes Human serine protease inhibitor WAP-four disulfide core domain 13 which is able to inhibit trypsin-like proteases like serine protease HtrA1 (BBa_K4165004).
Usage and Biology
This type of family encodes 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. 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.
