Peptidyl-prolyl cis-trans isomerase ESS1

UniProtKB accession:  P22696

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Essential PPIase specific for phosphoserine and phosphothreonine N-terminal to the proline residue. Required for efficient pre-mRNA 3'-end processing and transcription termination, probably by inducing conformational changes by proline-directed isomerization in the C-terminal domain (CTD) of RPB1, thereby altering cofactor binding with the RNA polymerase II transcription complex. Also targets the SIN3-RPD3 histone deacetylase complex (HDAC).
