Description:
ER alpha (Estrogen receptor alpha; also Estradiol receptor and NR3A1) is a 65-70 kDa member of the NR3 subfamily, nuclear hormone receptor family of proteins. It is widely expressed, and serves as a strong activator of estrogen-responsive genes. ER alpha is normally quiescent and bound to heat-shock proteins and immunophilins. Following beta -estradiol binding, it becomes activated, either homodimerizes or heterodimerizes with ER beta, and binds to DNA with multiple coactivators. Human ER alpha is 595 amino acids (aa) in length. It contains a DNA binding region (aa 185-250), three NLSs (aa 256-260; 266-271; 299-303), a steroid-binding site (aa 351-543), a dimerization motif (aa 497-518), and an O-GlcNAc attachment around Thr575. Major phosphorylation sites exist at Tyr537, Ser167 and Ser118. Multiple splice forms exist. There is an 80 kDa isoform that shows a substitution (duplication) of aa 412-517 for Asp411, a second isoform with a deletion of aa 255-366, a third isoform with a deletion of aa 152-412, and a fourth isoform that shows a Thr substitution for aa 152-595. Human ER alpha is only 46% aa identical to human ER beta. Over aa 1-116, human ER alpha shares 85% aa identity with mouse ER alpha.
