Abstract excerpt
Ess1 is an essential peptidylprolyl-cis/trans-isomerase in the yeast Saccharomyces cerevisiae. Ess1 and its human homolog, Pin1, bind to phospho-Ser-Pro sites within proteins, including the carboxyl-terminal domain (CTD) of Rpb1, the largest subunit of RNA polymerase II (pol II). Ess1 and Pin1 are thought to control mRNA synthesis by catalyzing conformational changes in Rpb1 that affect interaction of cofactors...
