J. Biochem. 227:19-26(1995). CC -!- FUNCTION: Acts by replacing the acid subunit in the crotoxin complex, CC inhibiting the PLA2 activity of the basic subunit. CNF is able to CC inhibit basic and acidic PLA2 from L.m.muta and B.jararacussu, even CC more efficiently. {ECO:0000269|PubMed:1949070, CC ECO:0000269|PubMed:7851385, ECO:0000269|PubMed:8195214}. CC -!- SUBUNIT: Homomer composed of six to eight subunits. CC -!- SUBCELLULAR LOCATION: Secreted. CC -!- TISSUE SPECIFICITY: Expressed by the liver and secreted in plasma. CC -!- SIMILARITY: Belongs to the CNF-like-inhibitor family. {ECO:0000305}.
