Previous GeneCards Identifiers for PTGER4 Gene
The protein encoded by this gene is a member of the G-protein coupled receptor family. This protein is one of four receptors identified for prostaglandin E2 (PGE2). This receptor can activate T-cell factor signaling. It has been shown to mediate PGE2 induced expression of early growth response 1 (EGR1), regulate the level and stability of cyclooxygenase-2 mRNA, and lead to the phosphorylation of glycogen synthase kinase-3. Knockout studies in mice suggest that this receptor may be involved in the neonatal adaptation of circulatory system, osteoporosis, as well as initiation of skin immune responses.

GeneCards Summary for PTGER4 Gene
PTGER4 (Prostaglandin E Receptor 4 (Subtype EP4)) is a Protein Coding gene. Diseases associated with PTGER4 include epididymal neoplasm and papillary thymic adenocarcinoma. Among its related pathways are Signaling by GPCR and Pathways in cancer. GO annotations related to this gene include G-protein coupled receptor activity and prostaglandin E receptor activity. An important paralog of this gene is TBXA2R.
UniProtKB/Swiss-Prot for PTGER4 Gene
Receptor for prostaglandin E2 (PGE2). The activity of this receptor is mediated by G(s) proteins that stimulate adenylate cyclase. Has a relaxing effect on smooth muscle. May play an important role in regulating renal hemodynamics, intestinal epithelial transport, adrenal aldosterone secretion, and uterine function
Prostanoid receptors are activated by the endogenous ligands prostaglandin (PG) D2, PGE2, PGF2alpha, PGH2, prostacyclin (PGI2) and thromboxane A2. Cyclooxygenase (COX) converts arachidonic acid to PGH2, from which the other prostaglandins are synthesized.
