Natarajan K, et al. (1999) Transcriptional activation by Gcn4p involves independent interactions with the SWI/SNF complex and the SRB/mediator. Mol Cell 4(4):657-64
Abstract: Mutations in three subunits of the SWI/SNF complex and in the Med2p subunit of the SRB/mediator of pol II holoenzyme impaired Gcn4p-activated transcription of HIS3 without reducing Gcn4p-independent transcription of this gene. Recombinant Gcn4p interacted with SWI/SNF and SRB/mediator subunits in cell extracts in a manner dependent on the same hydrophobic clusters in the Gcn4p activation domain; however, higher concentrations of Gcn4p were required for binding to SWI/SNF versus SRB/mediator subunits. In addition, SRB/mediator and SWI/SNF subunits did not coimmunopreciptate from the extracts. These findings, together with the fact that Gcn4p specifically interacted with purified SWI/SNF, strongly suggest that Gcn4p independently recruits SWI/SNF and holoenzyme to its target promoters in the course of activating transcription.
