Crystal Structure of Androgen Receptor DNA-Binding Domain Bound to a Direct Repeat Response Element

Structural highlights

1r4i is a 4 chain structure with sequence from Buffalo rat. The August 2007 RCSB PDB Molecule of the Month feature on Anabolic Steroids by David S. Goodsell is 10.2210/rcsb_pdb/mom_2007_8. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Disease

[ANDR_RAT] Note=Defects in Ar are a cause of androgen insensitivity. Rats with this syndrome are called testicular feminized (TFM).^[1]

Function

[ANDR_RAT] Steroid hormone receptors are ligand-activated transcription factors that regulate eukaryotic gene expression and affect cellular proliferation and differentiation in target tissues. Transcription factor activity is modulated by bound coactivator and corepressor proteins. Transcription activation is down-regulated by NR0B2. Activated, but not phosphorylated, by HIPK3 and ZIPK/DAPK3 (By similarity).^[2] ^[3]

Publication Abstract from PubMed

Steroid receptors bind as dimers to a degenerate set of response elements containing inverted repeats of a hexameric half-site separated by 3 bp of spacer (IR3). Naturally occurring selective androgen response elements have recently been identified that resemble direct repeats of the hexameric half-site (ADR3). The 3D crystal structure of the androgen receptor (AR) DNA-binding domain bound to a selective ADR3 reveals an unexpected head-to-head arrangement of the two protomers rather than the expected head-to-tail arrangement seen in nuclear receptors bound to response elements of similar geometry. Compared with the glucocorticoid receptor, the DNA-binding domain dimer interface of the AR has additional interactions that stabilize the AR dimer and increase the affinity for nonconsensus response elements. This increased interfacial stability compared with the other steroid receptors may account for the selective binding of AR to ADR3 response elements.
