Gene: LPAR4 (lysophosphatidic acid receptor 4) Homo sapiens
Symbol: LPAR4
Name: lysophosphatidic acid receptor 4
Description: This gene encodes a member of the lysophosphatidic acid receptor family. It may also be related to the P2Y receptors, a family of receptors that bind purine and pyrimidine nucleotides and are coupled to G proteins. The encoded protein may play a role in monocytic differentiation. [provided by RefSeq, Feb 2009]
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: G protein-coupled receptor 23; G-protein coupled receptor 23; GPR23; LPA receptor 4; LPA-4; LPA4; P2RY9; P2Y purinoceptor 9; P2Y5-LIKE; P2Y5-like receptor; P2Y9; purinergic receptor 9
