General annotation (Comments)

Function	F-box-like protein involved in the recruitment of the ubiquitin/19S proteasome complex to nuclear receptor-regulated transcription units. Plays an essential role in transcription activation mediated by nuclear receptors. Probably acts as integral component of the N-Cor corepressor complex that mediates the recruitment of the 19S proteasome complex, leading to the subsequent proteasomal degradation of N-Cor complex, thereby allowing cofactor exchange, and transcription activation. Ref.7
Subunit structure	Component of the N-Cor repressor complex, at least composed of NCOR1, NCOR2, HDAC3, TBL1X, TBL1XR1, CORO2A and GPS2. Probable component of some E3 ubiquitin ligase complex. Interacts with histones H2B and H4.
Subcellular location	Nucleus Probable.
Tissue specificity	Ubiquitous.
Domain	The F-box-like domain is related to the F-box domain, and apparently displays the same function as component of ubiquitin E3 ligase complexes By similarity.
Sequence similarities	Belongs to the WD repeat EBI family. Contains 1 F-box-like domain. Contains 1 LisH domain. Contains 8 WD repeats.
Sequence caution	The sequence AAH60320.1 differs from that shown. Reason: Contaminating sequence. Potential poly-A sequence.
