CC   -!- FUNCTION: Induces contraction of smooth muscle in isolated guinea
CC       pig urinary bladder (EC50=4.66 nM). Has no antimicrobial activity
CC       against the Gram-positive bacterium S.aureus, the Gram-negative
CC       bacterium E.coli and the yeast C.albicans. Elicits histamine
CC       release from rat peritoneal mast cells.
