F-box-like/WD repeat-containing protein TBL1X (TBL1X)

F-box-like protein involved in the recruitment of the ubiquitin/19S proteasome complex to atomic receptor-regulated transcription units (PubMed:14980219). Plays an important role in transcription activation mediated by nuclear receptors.

Probably acts as integral component of corepressor complexes that mediates the recruitment of the 19S proteasome complex, leading to the subsequent proteasomal degradation of transcription repressor complexes, thereby allowing cofactor exchange (PubMed:21240272). .
