  • Title: Characterization of a kallidin receptor in the eel intestine.
    Author: Cougnon N, Deacon CF, Lilley KS, Henderson IW.
    Journal: Agents Actions Suppl; 1992; 38 ( Pt 2)():382-9. PubMed ID: 1334338.
    Abstract:
    Edman degradation of an eel bradykinin (BK) -like peptide isolated and detected by gel filtration and HPLC and RIA gave an amino acid sequence of Arg1-Pro-Pro-Gly-X-Ser-Pro-Leu-Arg9. Kallidin but not BK and des-Arg9-BK contracted eel intestine. The contractile effect of kallidin was not decreased by B1 and B2 receptor antagonists (up to 10(-6)M), nor by anticholinergics, antiadrenergics, ganglion blockers and an angiotensin II receptor antagonist but was attenuated by 10(-5)M indomethacin. Kallidin appears to interact with a receptor different from the BK B1 and B2 receptor types and prostaglandins may participate in the response.
