CDC73

L000002792, YLR418C
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
Saccharomyces cerevisiae (S288c)

PCA

A Protein-Fragment Complementation Assay (PCA) is a protein-protein interaction assay in which a bait protein is expressed as fusion to one of the either N- or C- terminal peptide fragments of a reporter protein and prey protein is expressed as fusion to the complementary N- or C- terminal fragment of the same reporter protein. Interaction of bait and prey proteins bring together complementary fragments, which can then fold into an active reporter, e.g. the split-ubiquitin assay.

Genome-wide expression analysis of a Saccharomyces cerevisiae strain deleted for the Tup1p-interacting protein Cdc73p.

Kerkmann K, Lehming N

Tuplp is a general corepressor in Saccharomyces cerevisiae. We performed a split-ubiquitin screen with Tup1p as bait, in order to understand how Tuplp mediates repression. Cdc73p was the only component of a holoenzyme of transcription isolated as a Tuplp-interacting protein in this screen. Expression analysis of a strain deleted for CDC73 on a genome-wide scale revealed that Cdc73p is involved ... [more]

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.
