ID:LPAR2_HUMAN DESCRIPTION: RecName: Full=Lysophosphatidic acid receptor 2; Short=LPA receptor 2; Short=LPA-2; AltName: Full=Lysophosphatidic acid receptor Edg-4; FUNCTION: Receptor for lysophosphatidic acid (LPA), a mediator of diverse cellular activities. Seems to be coupled to the G(i)/G(o), G(12)/G(13), and G(q) families of heteromeric G proteins. Plays a key role in phospholipase C-beta (PLC-beta) signaling pathway. Stimulates phospholipase C (PLC) activity in a manner that is independent of RALA activation. SUBUNIT: Interacts with SLC9A3R2/NHERF2, MAGI3 and PLCB3. Interacts with RALA and ADRBK1. INTERACTION: P13569:CFTR; NbExp=4; IntAct=EBI-765995, EBI-349854; Q15599:SLC9A3R2; NbExp=2; IntAct=EBI-765995, EBI-1149760; SUBCELLULAR LOCATION: Cell surface. Cell membrane; Multi-pass membrane protein. Note=Prior to LPA treatment found predominantly at the cell surface but in the presence of LPA co-localizes with RALA in the endocytic vesicles. TISSUE SPECIFICITY: Expressed most abundantly in testes and peripheral blood leukocytes with less expression in pancreas, spleen, thymus and prostate. Little or no expression in heart, brain, placenta, lung, liver, skeletal muscle, kidney, ovary, small intestine, or colon. MISCELLANEOUS: PubMed:9525886 cDNA clone has a guanine nucleotide deletion that causes a frameshift near its C-terminal coding region. This likely reflects a somatic mutation in the ovary tumor cells from which the cDNA was isolated and may have altered the function of the encoded receptor, and contributed to transformation of the original ovary cells that formed a tumor. SIMILARITY: Belongs to the G-protein coupled receptor 1 family. SEQUENCE CAUTION: Sequence=AAC27728.1; Type=Frameshift; Positions=348;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
