RXR alpha (Retinoic acid receptor RXR alpha) is a 51KD member of the nuclear hormone receptor family, NR2 subfamily. This nuclear protein contains three domains: a modulating N-terminal domain, a DNA-binding domain and a C-terminal steroid-binding domain. The expression of RXR alpha is modulated differently during the activation of cell cycling. There are three retinoic acid receptors (RXR), RXR alpha, RXR, and RXR gamma encoded by the RXRA, RXRB, RXRG genes respectively. RXRs play an important role as promiscuous heterodimerization partners in modulating the activities of a number of nuclear receptors, which include RAR, thyroid hormone receptor, vitamin D receptor, peroxisome proliferator activated receptors, and COUP-TF. The poly6329 antibody recognizes human phosphorylated RXR alpha(Ser61) and has been shown to be useful for immunoflorence staining.

FAQs for RXR alpha/NR2B1 Antibody (NB100-78537). (Showing 1 - 2 of 2 FAQ).

  1. Can this antibody also be used for detection of chick RXR alpha (pSer61)?
    • We have not performed in house testing on chicken cells, but UniProt shows a high level of homology between human and chicken Retinoid X Receptor alpha, so there is a chance it can cross-react.
  2. Is the phosphorylation of Ser61 of the Retinoid X Receptor alpha an indication of its transciptional active state?
    • It would seem that phosphorylation of Ser61 of Retinoid X Receptor alpha is indicative of an active transcription state, as seen in the reference below: "Recently, it has been found that three additional residues (Ser61, Ser75 and Thr87) located in the same N-terminal domain can be also phosphorylated in response to retinoids (Gianni et al., 2003) and that this phosphorylation modulates the synergy between both heterodimeric partners for maximal transcriptional activity, very likely through helping the recruitment of coregulators." Here is a link to that reference.
