Gene name

GPER

Description

G protein-coupled estrogen receptor 1

Protein class

G-protein coupled receptors, Mapped to UniProt SWISS-PROT, Potential transmembrane proteins

Protein evidence

Low

Entrez gene summary

This gene is a member of the G-protein coupled receptor 1 family and encodes a multi-pass membrane protein that localizes to the endoplasmic reticulum. The protein binds estrogen, resulting in intracellular calcium mobilization and synthesis of phosphatidylinositol 3,4,5-trisphosphate in the nucleus. This protein therefore plays a role in the rapid nongenomic signaling events widely observed following stimulation of cells and tissues with estrogen. Alternate transcriptional splice variants which encode the same protein have been characterized. [provided by RefSeq, Jul 2008]
