Human Gene RXRB (uc011hgo.3) Description and Page Index
  Description: Homo sapiens retinoid X receptor, beta (RXRB), transcript variant 1, mRNA.
RefSeq Summary (NM_001270401): This gene encodes a member of the retinoid X receptor (RXR) family of nuclear receptors which are involved in mediating the effects of retinoic acid (RA). The encoded protein forms homodimers with the retinoic acid, thyroid hormone, and vitamin D receptors, increasing both DNA binding and transcriptional function on their respective response elements. This gene lies within the major histocompatibility complex (MHC) class II region on chromosome 6. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012].

DESCRIPTION: RecName: Full=Retinoic acid receptor RXR-beta; AltName: Full=Nuclear receptor subfamily 2 group B member 2; AltName: Full=Retinoid X receptor beta;
FUNCTION: 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 (By similarity). Specifically binds 9-cis retinoic acid (9C-RA).
SUBUNIT: Homodimer (By similarity). Heterodimer with a RAR molecule. Binds DNA preferentially as a RAR/RXR heterodimer.
INTERACTION: Q00975:CACNA1B; NbExp=3; IntAct=EBI-748576, EBI-1055161;
TISSUE SPECIFICITY: Expressed in a variety of tumor cell lines.
DOMAIN: Composed of three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal ligand-binding domain.
SIMILARITY: Belongs to the nuclear hormone receptor family. NR2 subfamily.
SIMILARITY: Contains 1 nuclear receptor DNA-binding domain.
SEQUENCE CAUTION: Sequence=BAD92481.1; Type=Erroneous initiation; Note=Translation N-terminally shortened;

ModBase Predicted Comparative 3D Structure on P28702
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
