Words similar to coactivators
Example sentences for: coactivators
How can you use “coactivators” in a sentence? Here are some example sentences to help you improve your vocabulary:
A number of RXR heterodimer complexes have been categorized as either permissive or non-permissive based on their responses to RXR ligands [ 1 ] . Although there are some reported discrepancies, the PPAR, FXR and NGF-IB/NURR1 complexes are generally considered permissive, while the non-permissive group includes the RAR, TR and VDR complexes (see [ 2 3 4 5 6 7 ] ). In the permissive complexes, coactivators can presumably bind to the AF-2 surface of both partners and binding to the RXR partner is stimulated by rexinoid agonists.
[ 18 ] . This constitutively activated Stat3 (a mutant produced by substitution of the cysteine residues within the COOH-terminal loop of the SH2 domain of Stat3) induces cellular transformation and tumor formation in nude mice [ 18 ] . The plasmids to express other coactivators (SRC-1, CBP/p300, TIF2 and PCAF) have been described elsewhere [ 29 30 ] .
More complex combinatorial effects of other coactivators or corepressors (e.g.
Stat3 is comparable to other coactivators on AR transcriptional activity: SRC-1, CBP/p300, TIF2, P/CAF.
Other NR coactivators include TRAP220 [ 7 ] , which is part of a larger complex (TRAP/DRIP/SMCC/mediator) that contacts the basal transcription machinery and PGC-1 [ 8 ] , a cold inducible coactivator that binds CBP and SRC-1 and proteins involved in RNA processing [ 9 ] . NR corepressors include NR corepressor (N-CoR) and silencing mediator of retinoid and thyroid responsive transcription (SMRT) [ 4 ] . Both N-CoR and SMRT repress transcription, at least in part, by binding to histone de-acetylases (HDACs) either directly or indirectly through other corepressor complex components.
