PG - d177-88 AB - Vitamin D exerts its genomic effects following binding to a specific receptor which is a member of the steroid hormone receptor superfamily. The vitamin D receptor (VDR) forms heterodimers with retinoid X receptors (RXRs) and the dimer then interacts with its cognate binding site, termed vitamin D response element (VDRE), to affect the transcription of target genes. Recent studies have identified novel sequence motifs for VDREs as well as novel protein-protein interactions involving the VDR. These will be reviewed with particular emphasis on the complex VDRE from the c-fos proto-oncogene promoter region and the inhibition of the vitamin D signal transduction pathway by the multifunctional protein, calreticulin. Thus research on the control of gene transcription by vitamin D reveals examples of molecular interplay between transcriptional regulatory pathways and provides new insight into the molecular mechanism of action of vitamin D.
