Induces contraction of rat ileum smooth muscle (EC(50)=2.73 uM) but has no activity towards rat smooth muscle from tail artery, urinary bladder or uterus. Binds to both bradykinin receptor B1 (BDKRB1) and B2 (BDKRB2); the effect via BDKRB1 is stronger. Expressed by the skin glands. Expression levels in inguinal glands and granular glands are virtually the same. Belongs to the frog skin active peptide (FSAP) family. Bradykinin-related peptide subfamily.
