Moderate to strong membranous and cytoplasmic positivity was seen in tumor tissues. Differential staining ranging from negative to strong membranous and cytoplasmic positivity was observed in breast, cervical, endometrial and liver cancers. Gliomas, prostate, lung and renal cancers were mainly negative.
G protein-coupled estrogen receptor 1 (HGNC Symbol)
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]
