Functioni

G-protein coupled estrogen receptor that binds to 17-beta-estradiol (E2) with high affinity, leading to rapid and transient activation of numerous intracellular signaling pathways. Stimulates cAMP production, calcium mobilization and tyrosine kinase Src inducing the release of heparin-bound epidermal growth factor (HB-EGF) and subsequent transactivation of the epidermal growth factor receptor (EGFR), activating downstream signaling pathways such as PI3K/Akt and ERK/MAPK. Mediates pleiotropic functions among others in the cardiovascular, endocrine, reproductive, immune and central nervous systems. Has a role in cardioprotection by reducing cardiac hypertrophy and perivascular fibrosis in a RAMP3-dependent manner. Regulates arterial blood pressure by stimulating vasodilation and reducing vascular smooth muscle and microvascular endothelial cell proliferation. Plays a role in blood glucose homeostasis contributing to the insulin secretion response by pancreatic beta cells. Triggers mitochondrial apoptosis during pachytene spermatocyte differentiation. Stimulates uterine epithelial cell proliferation. Enhances uterine contractility in response to oxytocin. Contributes to thymic atrophy by inducing apoptosis. Attenuates TNF-mediated endothelial expression of leukocyte adhesion molecules. Promotes neuritogenesis in developing hippocampal neurons. Plays a role in acute neuroprotection against NMDA-induced excitotoxic neuronal death. Increases firing activity and intracellular calcium oscillations in luteinizing hormone-releasing hormone (LHRH) neurons. Inhibits early osteoblast proliferation at growth plate during skeletal development. Inhibits mature adipocyte differentiation and lipid accumulation. Involved in the recruitment of beta-arrestin 2 ARRB2 at the plasma membrane in epithelial cells. Functions also as a receptor for aldosterone mediating rapid regulation of vascular contractibility through the PI3K/ERK signaling pathway. Involved in cancer progression regulation. Stimulates cancer-associated fibroblast (CAF) proliferation by a rapid genomic response through the EGFR/ERK transduction pathway. Associated with EGFR, may act as a transcription factor activating growth regulatory genes (c-fos, cyclin D1). Promotes integrin alpha-5/beta-1 and fibronectin (FN) matrix assembly in breast cancer cells.2 Publications

Expressed in epithelial cells, in pachytene spermatocytes (PS) (at protein level). Expressed strongly in vascular endothelial cells and poorly in vascular smooth muscle cells (VSMC). Expressed in the brain, lung, pituitary gland, adrenal medulla, renal pelvis and ovary. Expressed in CA1 hippocampus. Expressed weakly in heart, skeletal muscle and kidney.9 Publications

Interactioni

Subunit structurei

Homodimer (Probable). Heterodimer; heterodimerizes with other G-protein-coupled receptor (GPCRs) like CRHR1, HTR1A and PAQR8. Interacts with RAMP3. Interacts with KRT7 and KRT8. Interacts with EGFR; the interaction increases after agonist-induced stimulation in cancer-associated fibroblasts (CAF). Interacts with EGFR and ESR1 (By similarity). Interacts (via C-terminus tail motif) with DLG4 (via N-terminus tandem pair of PDZ domains); the interaction is direct and induces the increase of GPER1 protein levels residing at the plasma membrane surface in a estradiol-independent manner.By similarityCurated1 Publication
