Gene Symbol PTGER1
Protein Name prostaglandin E receptor 1 (subtype EP1), 42kDa
Synonyms EP1;
Species Homo sapiens
Ensembl Protein ENSP00000292513
InnateDB Gene IDBG-33370 (PTGER1)
Protein Structure
UniProt Annotation
Function Receptor for prostaglandin E2 (PGE2). The activity of this receptor is mediated by G(q) proteins which activate a phosphatidylinositol-calcium second messenger system. May play a role as an important modulator of renal function. Implicated the smooth muscle contractile response to PGE2 in various tissues.
Subcellular Localization Cell membrane; Multi-pass membrane protein.
Disease Associations
Tissue Specificity Abundant in kidney. Lower level expression in lung, skeletal muscle and spleen, lowest expression in testis and not detected in liver brain and heart.
