ΣE3, ΣE4, and ΣE3–4 are naturally occurring estrogen receptor (ER) isoforms, generated through differential splicing of the ERα primary transcript and abundantly expressed in embryonic rat pituitary. Studies in COS cells transfected with full-length ERα or its three splice variants fused to green fluorescent protein (GFP), revealed a different subcellular localization for each isoform. In the absence of estradiol, full-length ERα-GFP was predominantly nuclear, and ΣE3-GFP and ΣE4-GFP were present both in cytoplasm and nucleus, whereas ΣE3–4-GFP was predominantly cytoplasmic. Upon hormone treatment, a dramatic redistribution of full-length ERα-GFP and ΣE3-GFP, from a diffuse to punctate pattern, occurred within the nucleus. In contrast, the distribution of ΣE4-GFP and ΣE3–4-GFP was unaffected. Nuclear fractionation studies showed that full-length ER-α and ΣE3 displayed the same hormone-induced ability to tether to nuclear matrix, whereas nuclear ΣE4 appeared to remain loosely associated to functional nucle...
