Biol. Chem. 272:883-887(1997). CC -!- FUNCTION: RECEPTOR FOR PROSTAGLANDIN F2-ALPHA (PGF2-ALPHA). THE CC ACTIVITY OF THIS RECEPTOR IS MEDIATED BY G PROTEINS WHICH ACTIVATE CC A PHOSPHATIDYLINOSITOL-CALCIUM SECOND MESSENGER SYSTEM. INITIATES CC LUTEOLYSIS IN THE CORPUS LUTEUM. CC -!- SUBCELLULAR LOCATION: INTEGRAL MEMBRANE PROTEIN. CC -!- ALTERNATIVE PRODUCTS: 2 ISOFORMS; FP-A (SHOWN HERE) AND FP-B; CC ARE PRODUCED BY ALTERNATIVE SPLICING. FP-A AND FP-B HAVE IDENTICAL CC LIGAND BINDING PROPERTIES BUT DIFFERENT G PROTEIN COUPLING CC PROPERTIES. FP-B SHOWS AGONIST-INDEPENDENT CONSTITUTIVE ACTIVITY, CC BUT IS STILL RESPONSIVE TO AGONIST. CC -!- DEVELOPMENTAL STAGE: EXPRESSION IS HIGH IN THE MIDLUTEAL PHASE CC CORPUS LUTEUM AND DECREASES DURING LUTEOLYSIS. CC -!- SIMILARITY: BELONGS TO FAMILY 1 OF G-PROTEIN COUPLED RECEPTORS.
