Human GPER/GPR30 Antibody

GPER (G-Protein Coupled Estrogen Receptor 1; also GPR30, DRY12 and mER) is a 44 kDa, seven transmembrane (TM) member of the GPR-1 family of molecules. It is expressed on/in neurons, monocytes and endothelial cells. Its exact location is unclear; it has been described in both the cell membrane and ER. Human GPER is 375 amino acids (aa) in length. It contains an N-terminal extracellular region (aa 1‑62), a series of seven TM domains (aa 63‑327), and a C-terminal cytoplasmic tail (aa 328‑375). The initial function attributed to GPER was that of a membrane receptor for estrogen. There are two potential splice variants for GPER. One shows a deletion of aa 32-49, while a second shows a 99 aa substitution for aa 308‑375. Over aa 1‑62, human GPER shares 57% aa identity with mouse GPER.
