WAP-four disulphide core domain 10A serine protease inhibitor.

This basic part encodes Human serine protease inhibitor WAP-four disulfide core domain 10A which is able to inhibit HtrA1 (BBa_K4165004).

Usage and Biology

This gene 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. 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].
