Related Product Information for anti-RXRalpha antibody

The human retinoid X receptors (RXRs) are encoded by three distinct genes (RXRalpha, RXRbeta, and RXRgamma) and bind selectively and with high affinity to the vitamin A derivative, 9-cis-retinoic acid. RXRs are type-II nuclear hormone receptors that are largely localized to the nuclear compartment independent of ligand binding. Nuclear RXRs form heterodimers with nuclear hormone receptor subfamily 1 proteins, including thyroid hormone receptor, retinoic acid receptors, vitamin D receptor, peroxisome proliferator-activated receptors, liver X receptors, and farnesoid X receptor. Since RXRs heterodimerize with multiple nuclear hormone receptors, they play a central role in transcriptional control of numerous hormonal signaling pathways by binding to cis-acting response elements in the promoter/enhancer region of target genes. Retinoid X receptor alpha (RXRalpha) is the founding RXR family member and is predominantly expressed in liver, kidney, epidermis, intestine and a variety of tissues. Knockout of the murine rxralpha gene results in embryonic lethality tentatively due to myocardial hypoplasia, which demonstrates the importance of RXRalpha to retinoid signaling in vivo. Biochemical evidence suggests that RXRalpha transcriptional activity is post-translationally regulated through the Ras-Raf-MAPK signaling cascade. MAPK-dependent phosphorylation of RXRalpha directly abrogates the ability of RXRalpha to associate with nuclear receptor coactivators.

NCBI Description

Retinoid X receptors (RXRs) and retinoic acid receptors (RARs) are nuclear receptors that mediate the biological effects of retinoids by their involvement in retinoic acid-mediated gene activation. These receptors function as transcription factors by binding as homodimers or heterodimers to specific sequences in the promoters of target genes. The protein encoded by this gene is a member of the steroid and thyroid hormone receptor superfamily of transcriptional regulators. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2014]

Uniprot Description

RXRA: 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. Homodimer. Heterodimer with RARA; required for ligand- dependent retinoic acid receptor transcriptional activity. Heterodimer with PPARA (via the leucine-like zipper in the LBD); the interaction is required for PPARA transcriptional activity. Also heterodimerizes with PPARG. Interacts with NCOA3 and NCOA6 coactivators. Interacts with FAM120B. Interacts with PELP1, SENP6, SFPQ, DNTTIP2 and RNF8. Interacts (via the DNA binding domain) with HCV core protein; the interaction enhances the transcriptional activities of the RXRA/RARA and the RXRA/PPARA heterodimers. Interacts with PRMT2. Interacts with ASXL1 and NCOA1. Highly expressed in liver, also found in lung, kidney and heart. Belongs to the nuclear hormone receptor family. NR2 subfamily.
