Summaries for LPAR2 Gene

Entrez Gene Summary for LPAR2 Gene

  • 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, Jul 2008]

GeneCards Summary for LPAR2 Gene

LPAR2 (Lysophosphatidic Acid Receptor 2) is a Protein Coding gene. Among its related pathways are Peptide ligand-binding receptors and Interleukin-3, 5 and GM-CSF signaling. GO annotations related to this gene include G-protein coupled receptor activity and PDZ domain binding. An important paralog of this gene is LPAR1.

UniProtKB/Swiss-Prot for LPAR2 Gene

  • 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.

    • 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.
