STRUCTURE OF 17-EPIESTRIOL-BOUND ESTROGEN RECEPTOR BETA LBD IN COMPLEX WITH LXXLL MOTIF FROM NCOA5STRUCTURE OF 17-EPIESTRIOL-BOUND ESTROGEN RECEPTOR BETA LBD IN COMPLEX WITH LXXLL MOTIF FROM NCOA5
Structural highlights
2j7y is a 2 chain structure with sequence from Buffalo rat. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
[ESR2_RAT] Binds estrogens with an affinity similar to that of ER-alpha, and activates expression of reporter genes containing estrogen response elements (ERE) in an estrogen-dependent manner. Isoform 3 and isoform 4 are unable to bind DNA and activate transcription due to the truncation of the DNA binding domain. Isoform 2 shows loss of ligand binding affinity and suppresses ER-alpha and ER-beta1 mediated transcriptional activation and may act as a dominant negative regulator of estrogen action. [NCOA5_HUMAN] Nuclear receptor coregulator that can have both coactivator and corepressor functions. Interacts with nuclear receptors for steroids (ESR1 and ESR2) independently of the steroid binding domain (AF-2) of the ESR receptors, and with the orphan nuclear receptor NR1D2. Involved in the coactivation of nuclear steroid receptors (ER) as well as the corepression of MYC in response to 17-beta-estradiol (E2).[1]
