[[http://www.uniprot.org/uniprot/VDR_HUMAN VDR_HUMAN]] Defects in VDR are the cause of rickets vitamin D-dependent type 2A (VDDR2A) [MIM:[http://omim.org/entry/277440 277440]]. A disorder of vitamin D metabolism resulting in severe rickets, hypocalcemia and secondary hyperparathyroidism. Most patients have total alopecia in addition to rickets.<ref>PMID:2849209</ref><ref>PMID:8381803</ref><ref>PMID:1652893</ref><ref>PMID:2177843</ref><ref>PMID:8106618</ref><ref>PMID:8392085</ref><ref>PMID:7828346</ref><ref>PMID:8675579</ref><ref>PMID:8961271</ref><ref>PMID:9005998</ref> | |||

The | [[http://www.uniprot.org/uniprot/RXRA_HUMAN RXRA_HUMAN]] Receptor for retinoic acid. Retinoic acid receptors bind as heterodimers to their target response elements in response to their ligands, all-trans or 9-cis retinoic acid, and regulate gene expression in various biological processes. The RAR/RXR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. The high affinity ligand for RXRs is 9-cis retinoic acid. RXRA serves as a common heterodimeric partner for a number of nuclear receptors. The RXR/RAR heterodimers bind to the retinoic acid response elements (RARE) composed of tandem 5'-AGGTCA-3' sites known as DR1-DR5. In the absence of ligand, the RXR-RAR heterodimers associate with a multiprotein complex containing transcription corepressors that induce histone acetylation, chromatin condensation and transcriptional suppression. On ligand binding, the corepressors dissociate from the receptors and associate with the coactivators leading to transcriptional activation. The RXRA/PPARA heterodimer is required for PPARA transcriptional activity on fatty acid oxidation genes such as ACOX1 and the P450 system genes.<ref>PMID:10195690</ref><ref>PMID:11162439</ref><ref>PMID:11915042</ref><ref>PMID:20215566</ref> [[http://www.uniprot.org/uniprot/VDR_HUMAN VDR_HUMAN]] 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. Recruited to promoters via its interaction with the WINAC complex subunit BAZ1B/WSTF, which mediates the interaction with acetylated histones, an essential step for VDR-promoter association. Plays a central role in calcium homeostasis.<ref>PMID:16252006</ref><ref>PMID:10678179</ref><ref>PMID:15728261</ref><ref>PMID:16913708</ref> | ||
