Function

SP2_ANOGA Serine protease inhibitor that functions in the melanization-mediated immune response (PubMed:16113656, PubMed:20953892, PubMed:33520733, PubMed:33045027, PubMed:21465556, PubMed:25525260). By preventing the activation of phenoloxidases through the inhibiting of serine proteases CLIPB9 and CLIPB10, negatively regulates melanization in the hemolymph (PubMed:16113656, PubMed:20953892, PubMed:33520733, PubMed:33045027, PubMed:21465556, PubMed:25525260). By preventing melanization, has a detrimental role during P.berghei parasite mediated-infection and invasion of the mosquito midgut (PubMed:16113656).^{[1] [2] [3] [4] [5] [6]}
