WAP-four disulfide core domain 6 serine protease inhibitor.

This basic part encodes Human serine protease inhibitor WAP-four disulfide core domain 6 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 has 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].
