CC -!- FUNCTION: Inhibits thermolysin, bacillolysin and pseudolysin, CC B.polymyxa metalloprotease and human MMP1 and MMP3. No activity on CC trypsin or cysteine protease papain. {ECO:0000269|PubMed:15115439, CC ECO:0000269|PubMed:9738891}. CC -!- DEVELOPMENTAL STAGE: Expressed in fat body of last instar larvae. CC {ECO:0000269|PubMed:34443685}. CC -!- INDUCTION: During humoral immune response (PubMed:9738891). By CC lipopolysaccharide (LPS) (PubMed:15115439). Induced by A.niger alpha- CC 1,3-glucan (PubMed:34443685). {ECO:0000269|PubMed:15115439, CC ECO:0000269|PubMed:34443685, ECO:0000269|PubMed:9738891}. CC -!- PTM: Cleaved. {ECO:0000305}. CC -!- PTM: Five disulfide bonds are present. When artificially cleaved by CC thermolysin between Asn-56 and Ile-57, the two obtained chains (called CC heavy and light chains) remain linked. CC -!- PTM: The N-terminus is blocked.
