Function
VDRA_DANRE Nuclear hormone receptor. Transcription factor that mediates the action of vitamin D3 by controlling the expression of hormone sensitive genes. Regulates transcription of hormone sensitive genes via its association with the WINAC complex, a chromatin-remodeling complex. Plays a central role in calcium homeostasis.[1]
Publication Abstract from PubMed
1alpha,20S-Dihydroxyvitamin D3 [1,20S(OH)2D3], a natural and bioactive vitamin D3 metabolite, was chemically synthesized for the first time. X-ray crystallography analysis of intermediate 15 confirmed its 1alpha-OH configuration. 1,20S(OH)2D3 interacts with the vitamin D receptor (VDR), with similar potency to its native ligand, 1alpha,25-dihydroxyvitamin D3 [1,25(OH)2D3] as illustrated by its ability to stimulate translocation of the VDR to the nucleus, stimulate VDRE-reporter activity, regulate VDR downstream genes (VDR, CYP24A1, TRPV6 and CYP27B1), and inhibit the production of inflammatory markers (IFNgamma and IL1beta). However, their co-crystal structures revealed differential molecular interactions of the 20S-OH moiety and the 25-OH moiety to the VDR, which may explain some differences in their biological activities. Furthermore, this study provides a synthetic route for the synthesis of 1,20S(OH)2D3 using the intermediate 1alpha,3beta-diacetoxypregn-5-en-20-one (3), and provides a molecular and biological basis for the development of 1,20S(OH)2D3 and its analogs as potential therapeutic agents.
