Induces contraction of rat ileum smooth muscle (EC(50)=2.73 uM) but has no activity towards smooth muscle from tail artery, urinary bladder or uterus up to concentrations of 100 uM. Binds to both bradykinin receptor B1 (BDKRB1) and B2 (BDKRB2); the effect via BDKRB1 is stronger. [Val1,Hyp2,Thr6]-bradykinin-Gln,Ser: Induces contraction of rat ileum smooth muscle (EC(50)=710 nM) but has no activity towards smooth muscle from tail artery, urinary bladder or uterus up to concentrations of 100 uM. Binds to both bradykinin receptor B1 (BDKRB1) and B2 (BDKRB2); the effect via BDKRB1 is stronger (PubMed:24394432). Induces contraction of guinea pig ileum smooth muscle (PubMed:16797783). Expressed by the skin glands. [Val1,Thr6]-bradykinyl-Gln,Ser. [Val1,Hyp2,Thr6]-bradykinyl-Gln,Ser. [Val1,Thr6]-bradykinin. [Val1,Hyp2,Thr6]-bradykinin. [Val1,Thr6]-bradykinyl-Gln,Ser. [Val1,Hyp2,Thr6]-bradykinyl-Gln,Ser. [Val1,Thr6]-bradykinin. [Val1,Hyp2,Thr6]-bradykinin. Belongs to the frog skin active peptide (FSAP) family. Bradykinin-related peptide subfamily.
