Influence Of The Pre-Initiation Complex On Mediator Recruitment In Saccharomyces Cerevisiae, Elisabeth Rose Knoll
Legacy Theses & Dissertations (2009 - 2024)
The Mediator complex plays a central, highly conserved role in eukaryotic transcription by RNA Polymerase II (Pol II) by stimulating the cooperative assembly of a pre-initiation complex (PIC) and recruitment of Pol II for gene activation. Mediator recruitment has generally been ascribed to sequence-specific activators engaging subunits from the tail module which in turn function to recruit the middle and head for complete assembly at the UAS. Mediator subunits of the middle and head then bridge the enhancer to connect with the PIC at the core promoter. It is reported that Mediator recruitment at the UAS preferentially occurs at SAGA-dependent, …
