[[http://www.uniprot.org/uniprot/PGPLC_DROME PGPLC_DROME]] Major activator of the imd/Relish pathway and is likely to encode a pattern recognition molecule for the humoral immune response. Required for Relish processing and nuclear translocation following proteolytic cleavage. Involved in the response to lipopolysaccharide (LPS) and peptidoglycan of Gram-negative bacteria. The different isoforms probably display different recognition capabilities to various microbial patterns. Isoform a and isoform x mediate the induction by LPS and Gram-negative bacteria, while isoform x mediates the induction by peptidoglycan.<ref>PMID:11872802</ref> <ref>PMID:12777387</ref> <ref>PMID:16006509</ref>
