Has kinin-like biological properties. Causes contraction of isolated guinea pig ileum and relaxation of rat duodenum. Has a number of hypotensive properties: decreases arterial blood pressure and increases capillary permeability. Induces edema when injected into hindpaw of rat. May target bradykinin receptors (BDKRB). Does not lyse unfibrinolysed blood. Expressed by the venom gland. The molecular weight of about 4 kDa suggests that the mature peptide comprises about 36 amino acid residues. Belongs to the bradykinin-related peptide family.
