J Biol Chem . 1997 Jun; 272(23):14592-9. PMID: 9169418
To investigate a potential ligand-dependent transcriptional activation domain (AF-2) in the C-terminal region of the human vitamin D receptor (hVDR), two conserved residues, Leu-417 and Glu-420, were replaced with alanines...

Mol Endocrinol . 1996 Dec; 10(12):1617-31. PMID: 8961271
Hereditary hypocalcemic vitamin D-resistant rickets is attributable to defects in the nuclear receptor for 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3]. Two novel point mutations (I314S and R391C) identified in the hormone-binding domain of...

Proc Natl Acad Sci U S A . 1996 Apr; 93(8):3519-24. PMID: 8622969
The potential functional significance of human 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] receptor (hVDR) phosphorylation at Ser-208 was evaluated by cotransfecting COS-7 kidney cells with hVDR constructs and the catalytic subunit of human...

J Biol Chem . 1996 Mar; 271(9):5143-9. PMID: 8617794
The significance of conserved cysteines at positions 288, 337, and 369 in the hormone binding domain of the human vitamin D receptor was evaluated by individual site-directed mutagenesis to glycine....

Mol Endocrinol . 1995 Sep; 9(9):1166-79. PMID: 7491109
Residues located between amino acids 244 and 263 in the human vitamin D receptor (hVDR) show extensive homology with other members of the steroid/thyroid/retinoid hormone receptor superfamily. The corresponding region...

The nuclear vitamin D receptor (VDR) binds the 1,25-dihydroxyvitamin D3 [1,25(OH)2D3]hormone with high affinity and elicits its actions to regulate gene expression in target cells by binding to vitamin D-responsive...

J Nutr . 1995 Jun; 125(6 Suppl):1690S-1694S. PMID: 7782928
Recent studies have identified a heterodimer of the vitamin D receptor (VDR) and the retinoid X receptor (RXR) as the active complex for mediating positive transcriptional effects of 1,25-dihydroxyvitamin D3...
