SPT4

transcription elongation factor SPT4, L000002030, YGR063C
Component of the universally conserved Spt4/5 complex (DSIF complex); the complex has multiple roles in concert with RNA polymerases I and II, including regulation of transcription elongation, RNA processing, quality control, and transcription-coupled DNA repair; Spt4p also localizes to kinetochores and heterochromatin and affects chromosome dynamics and silencing; required for transcription through lengthy trinucleotide repeats in ORFs or non-protein coding regions
Saccharomyces cerevisiae (S288c)

MFT1

MFT52, L000001099, YML062C
Subunit of the THO complex; THO is a nuclear complex comprised of Hpr1p, Mft1p, Rlr1p, and Thp2p, that is involved in transcription elongation and mitotic recombination; involved in telomere maintenance
Saccharomyces cerevisiae (S288c)

Synthetic Lethality

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

Molecular evidence for a positive role of Spt4 in transcription elongation.

We have previously shown that yeast mutants of the THO complex have a defect in gene expression, observed as an impairment of lacZ transcription. Here we analyze the ability of mutants of different transcription elongation factors to transcribe lacZ. We found that spt4Delta, like THO mutants, impaired transcription of lacZ and of long and GC-rich DNA sequences fused to the ... [more]
