Pin1 modulates the dephosphorylation of the RNA polymerase II C-terminal domain by yeast Fcp1.

Abstract

The reversible phosphorylation of serine and threonine residues N-terminal to proline (pSer/Thr-Pro) is an important signaling mechanism in the cell. The pSer/Thr-Pro moiety exists in the two distinct cis and trans conformations, whose conversion is catalyzed by the peptidyl-prolyl isomerase (PPIase) Pin1. Among others, Pin1 binds to the phosphorylated C… (More)
