Mechanism and regulation of transcriptional elongation by RNA polymerase II

D Reines et al. Curr Opin Cell Biol. 1999 Jun.

Abstract

Over the past few years, biochemical and genetic studies have shed considerable light on the structure and function of the RNA polymerase II (pol II) elongation complex and the transcription factors that control it. Novel elongation factors have been identified and their mechanisms of action characterized in increasing detail; new insights into the biological roles of elongation factors have been gained from genetic studies of the regulation of mRNA synthesis in yeast; and intriguing links between the pol II elongation machinery and the pathways of DNA repair and recombination have emerged.

Genetic interactions between pol II and elongation factors in yeast. Genetic interaction (arrows) between pol II subunits (rectangles), elongation factors (square, triangle) and chromatin-related transcription factors (circle) that have been recently shown in S. cerevisiae are depicted. A factor involved in elongation and DNA recombination (HPR1, oval) has also been shown to interact with RNA pol II in yeast.

This paper presents evidence that some transcriptional activation domains have distinct subdomains responsible for their effects on transcription initiation and elongation. These findings provide important insight into the nature of DNA binding transactivators and how they function in the regulation of elongation by pol II. - PMC - PubMed
