ESS1/YJR017C Summary Help

Standard Name ESS1 1
Systematic Name YJR017C
Alias PTF1 2 , PIN1
Feature Type ORF, Verified
Description 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 (3, 4, 5)
