May act as a serine protease inhibitor, since it possess the kazal serine protease inhibitor signature (Probable). The recombinant peptide does not produce toxic effects on insects (PubMed:31870846). Expressed by the venom gland. Monoisotopic mass. The peptide presented here consists of a single Kazal domain but is suggested to be derived from a multidomain Kazal protein after proteolytic cleavage.
