Promoter selective transcriptional synergy mediated by sterol regulatory element binding protein and Sp1: a critical role for the Btd domain of Sp1.


Cellular cholesterol and fatty acid levels are coordinately regulated by a family of transcriptional regulatory proteins designated sterol regulatory element binding proteins (SREBPs). SREBP-dependent transcriptional activation from all promoters examined thus far is dependent on the presence of an additional binding site for a ubiquitous coactivator. In… (More)
