| A search for novel coregulators of ERR gamma led to the identification of receptor interacting protein 140 as a potent corepressor and peroxisome proliferator activated receptor gamma coactivator 1 as a potent coactivator of ERR gamma . ^^^ Because ERR gamma shows a similar tissue distribution as peroxisome proliferator activated receptor gamma coactivator 1 and receptor interacting protein 140 , these two coregulators may act as key components of ERR gamma mediated transcription . . ^^^ |
