Vitamin D receptor contains multiple dimerization interfaces that are functionally different.

The vitamin D receptor mediates the signal of 1 alpha, 25-dihydroxyvitamin D3 by binding to vitamin D responsive elements in DNA as a homodimer or as a heterodimer composed of one vitamin D receptor subunit and one retinoid X receptor subunit. We have mapped the dimerization interfaces of the vitamin D receptor that is involved in homo- or heterodimer formation in the absence of DNA. While dele...

The Association of Vitamin D Receptor Gene BsmI Polymorphism with Multiple Sclerosis in Iranian Patients

Background & Aims: 1,25-dihydroxyvitamin D3 (1,25 (OH)2 D3), the biologically active form of vitamin D, exerts an immunosuppressive effect through binding to its specific nuclear receptor. The present case-control study was done to examine the possible association of BsmI polymorphism in vitamin D receptor gene (VDR gene) with severity of multiple sclerosis (MS). Methods: 267 Iranian patients w...

G-protein Coupled Receptor Dimerization

A growing body of evidence suggests that GPCRs exist and function as dimers or higher oligomers. The evidence for GPCR dimerization comes from biochemical, biophysical and functional studies. In addition, researchers have shown the occurrence of heterodimerization between different members of the GPCR family. Two receptors can interact with each other to make a dimer through their extracellular...

Vitamin D receptor and vitamin D metabolizing enzymes are expressed in the human male reproductive tract.

BACKGROUND The vitamin D receptor (VDR) is expressed in human testis, and vitamin D (VD) has been suggested to affect survival and function of mature spermatozoa. Indeed, VDR knockout mice and VD deficient rats show decreased sperm counts and low fertility. However, the cellular response to VD is complex, since it is not solely dependent on VDR expression, but also on cellular uptake of circula...

Polymorphisms within Exon 9, But Not Intron 8, of the Vitamin D Receptor Gene Are Associated with Asthma

Objective(s) Deregulation of the immune system through allied factors and cytokine responses are thought to be important contributors to the pathogenesis of asthma. Vitamin D3 and its nuclear receptor appear to be factors that maybe involved in regulating immune responses during the progression of asthma. The aim of this study was to investigate the association between polymorphisms in intron ...
