Source Prostaglandin F2 alpha was found to be accummulating in human semen in an amount of about 2 microgram per ml Bergstrom_S . In most animal tissues prostanoids are synthesized enzymatically de novo upon physiological and pathological stimulations, and this is also the case of prostaglandin F2 alpha .
Chemical Synthesis Corey_EJ et al.
Metabolism Prostaglandin F synthase reduces 9,11-endoperoxide of prostaglandin H2 requiring NADPH, and produces prostaglandin F2 alpha . The same enzyme also reduces 9-keto group of prostaglandin D2 producing 11 beta -prostaglandin F2 Urade_Y et al..
Biological Activity Prostaglandin F2 alpha exhibits various biological activities such as uterine contraction, gastrointestinal contraction, bronchoconstriction, luteolysis and vasoconstriction Bergstrom_S et al.. Prostaglandin F2 alpha is a ligand to a receptor (FP) present in the cell membrane Negishi_M et al..
Genetic Information cDNA for prostaglandin F synthase was cloned from bovine lung Urade_Y et al.. cDNA for prostaglandin F2 alpha receptor (FP) was cloned, and its 7ptransmembrane structure was reported Negishi_M et al..
