Unitz domains act as protease inhibitors . As talked about previously,snake and spider venoms include proteins with Kunitz domains . Some domains inhibit trypsin or chymotrypsin via P,whilst other people lack antiprotease activity but have neurotoxic effects by acting as potassium channel blockers . Peigneur and colleagues recently reported a sea anemone Kunitz domain protein,APEKTx (Anthopleura elegantissima potassium channel toxin which had dual functions. It exhibited each trypsininhibitor activity and selectively blocked the Kv. form of voltagegated potassium channels. Additionally,not all Kunitz protease inhibitors act by means of the PPharo et al.
