Systematic name YJR017C
Gene name ESS1
Aliases PIN1, PTF1
Feature type ORF, Verified
Coordinates Chr X:467033..466521
Primary SGDID S000003778


Description of YJR017C: Peptidylprolyl-cis/trans-isomerase (PPIase); specific for phosphorylated serine and threonine residues N-terminal to proline; regulates phosphorylation of the RNAP II large subunit (Rpo21p) C-terminal domain (CTD); associates with phospho-Ser5 form of RNAP II in vivo; regulates phosphorylation of Ser7 within CTD; present along entire coding length of genes; represses initiation of CUTs; required for efficient termination of mRNA transcription and trimethylation of histone H3[1][2][3]
