About This Section
| EntrezGene summary for LPAR2: This gene encodes a member of family I of the G protein-coupled receptors, as well as the EDG family of proteins. This protein functions as a lysophosphatidic acid (LPA) receptor and contributes to Ca2+ mobilization, a critical cellular response to LPA in cells, through association with Gi and Gq proteins. An alternative splice variant has been described but its full length sequence has not been determined. [provided by RefSeq] UniProtKB/Swiss-Prot: LPAR2_HUMAN, Q9HBW0Function: 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 pathwayGene Wiki entry for LPAR2 (EDG4) |

About This Section
| UniProtKB/Swiss-Prot: LPAR2_HUMAN, Q9HBW0 (See
protein sequence)Recommended Name: Lysophosphatidic acid receptor 2 Size: 351 amino acids; 39084 Da
Subunit: Interacts with SLC9A3R2/NHERF2, MAGI3 and PLCB3
Subcellular location: Cell membrane; Multi-pass membrane protein
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
