RN [2] RP NUCLEOTIDE SEQUENCE [MRNA], AND ALTERNATIVE SPLICING. RC TISSUE=Corpus luteum; RX MEDLINE=97150841; PubMed=8995377; DOI=10.1074/jbc.272.2.883; RA Pierce K.L., Bailey T.J., Hoyer P.B., Gil D.W., Woodward D.F., RA Regan J.W.; RT "Cloning of a carboxyl-terminal isoform of the prostanoid FP RT receptor."; RL J. 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: Cell membrane; Multi-pass membrane protein. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Comment=Isoform FP-A and isoform FP-B have identical ligand CC binding properties but different G protein coupling properties; CC Name=FP-A; CC IsoId=Q28905-1; Sequence=Displayed; CC Name=FP-B; CC IsoId=Q28905-2; Sequence=VSP_001951; CC Note=Shows agonist-independent constitutive activity, but is CC 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 the G-protein coupled receptor 1 family.
