The function of GPR87 (G protein-coupled receptor 87, ENSG00000138271) is as follows. Receptor for lysophosphatidic acid (LPA) (PubMed:17905198). Necessary for p53/TP53-dependent survival in response to DNA damage (PubMed:19602589). Promotes the Hippo-YAP signaling pathway and thereby modulates glycolysis and oxidative stress production by the regulation of hexokinase-2/HK2 (PubMed:35843477). {ECO:0000269|PubMed:17905198, ECO:0000269|PubMed:19602589, ECO:0000269|PubMed:35843477}.
