Wayne State University Dissertations
My Ph.D. dissertation work is focused on studying the role of promoter-bound transcription initiation factors involved in gene looping. In this study we showed that the RNAP II subunit Rpb4 has a significant effect on termination of transcription. Gene looping is disrupted in the absence of Rpb4. Rpb4 shows a strong physical interaction with the Mediator subunit Srb5. Mediator subunit Srb5 crosslinked to the 5' and 3' ends of INO1 and CHA1 genes and is required for proper termination of transcription of these genes. Srb5 affected termination of transcription through its interaction with the CF1 complex. Srb5 interaction with the …
