Recombinant human RXR alpha/RXRA protein

Can be stored at +2C to +8C for 1 week. For long term storage, aliquot and store at -20C to -80C. Avoid repeated freezing and thawing cycles.

The retinoid X receptor (RXR) is a pleiotropic nuclear receptor transcription factor that interacts with a variety of nuclear receptor dimeric partner. RXR binds cognate response elements as a homodimer in the presence of its ligand, 9-cis retinoic acid, or as a heterodimer with other members of the nuclear hormone receptor superfamily including retinoic acid receptors (RAR), thyroid hormone receptors (TR), vitamin D receptors and peroxisome proliferators-activated receptors (PPAR). The RXR family includes three difference isoforms ; RXR alpha, beta, gamma. Human RXR alpha gene is localized on 9q34. 9 and encodes two major isoforms (RXR alpha1, RXR alpha2). The DNA binding domain of RXR (111-228aa) was over expressed in E. coli and purified by using conventional column chromatography techniques.
