Strongly inhibits its own venom PLA2 and all other PLA2s tested including Elapid, Crotalid and Viperid venom PLA2s, as well as honeybee PLA2s. Heterotrimer of 2 subunits A and 1 subunit B. Secreted in blood plasma. Expressed by the liver. N-glycosylation is not important for activity, since deglycosylation does not change its PLA2 inhibitory activity. Belongs to the CNF-like-inhibitor family.
