Epitopes of the nuclear ERα recognized by available anti-ERαAbs that also recognize mERα. These results are compiled from experiments on both unfixed and fixed cells which sometimes differed in their intensity of staining for a given Ab (Pappas et al. 1994, 1995a,Pappas et al. b; Watson et al. 1995; Norfleet et al. 1999a,b). The location of the epitopes are shown by the various symbols above the map of the peptide. Abs recognizing each epitope are listed above the symbol; their sources and descriptions are in the Methods section. The established functional domain structure of intracellular ERα is shown for reference.
