This is the very C-terminal region of a subfamily of nuclear receptors that includes oestrogen receptors and other subfamily 3 group A members. The actual function of this region is not known, but the domain is absent from all the other types of nuclear receptors. Oestrogen receptors modulate AP-1-dependent transcription [1] through two distinct mechanisms: via protein-protein interactions on DNA; and via non-genomic actions. The mechanism used depends on the cellular localisation of the receptor. In addition to the more extensively studied cross-talk on DNA, additional non-genomic actions might be very important in target tissues in which membrane-associated ERs are found. These non-genomic actions probably contribute to the overall physiological responses mediated by ligand-bound ERs [2] and might possibly be mediated via this C-terminal domain.
This domain is found in steroid/nuclear receptor coactivators and contains two LXXLL motifs that are involved in receptor binding [1]. The family includes SRC-1/NcoA-1, NcoA-2/TIF2, pCIP/ACTR/GRIP-1/AIB1.
