CDC73/YLR418C Summary Help

Standard Name CDC73 1
Systematic Name YLR418C
Feature Type ORF, Verified
Description Component of the Paf1p complex; binds to and modulates the activity of RNA polymerases I and II; required for expression of certain genes, modification of some histones, and telomere maintenance; involved in transcription elongation as demonstrated by the G-less-based run-on (GLRO) assay; protein abundance increases in response to DNA replication stress; human homologue, parafibromin, is a tumour suppressor linked to breast, renal and gastric cancers (2, 3, 4, 5, 6, 7, 8, 9, 10)
