Summary: Enables serine-type endopeptidase activity. Involved in several processes, including Toll receptor ligand protein activation cascade; defense response to other organism; and positive regulation of antimicrobial peptide production. Predicted to be located in extracellular region. Predicted to be active in extracellular space. Is expressed in adult head; embryonic/larval fat body; and wing disc.
