Rapidly inactivates both channel catfish herpesvirus (ED(50)=4 uM) and frog virus 3 (ED(50)=13 uM) over a wide temperature range (PubMed:15193922). Seems to disrupt the membranes by adopting an alpha helical conformation (PubMed:11739390). Expressed in gill, skin, intestine, spleen, anterior kidney, and blood cells. Belongs to the pleurocidin family.
