Functional interaction of yeast pre-mRNA 3' end processing factors with RNA polymerase II.

Abstract

The RNA polymerase II CTD is essential for 3' end cleavage of metazoan pre-mRNAs and binds 3' end processing factors in vitro. We show genetic and biochemical interactions between the CTD and the Pcf11 subunit of the yeast cleavage/polyadenylation factor, CFIA. In vitro binding to Pcf11 required phosphorylation of the CTD on Ser2 in the YSPTSPS heptad… (More)
