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

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.

SPT4, SPT5 and SPT6 interactions: effects on transcription and viability in Saccharomyces cerevisiae.

Swanson MS, Winston F

The SPT4, SPT5 and SPT6 genes of Saccharomyces cerevisiae were identified originally by mutations that suppress delta insertion mutations at HIS4 and LYS2. Subsequent analysis has demonstrated that spt4, spt5 and spt6 mutations confer similar pleiotropic phenotypes. They suppress delta insertion mutations by altering transcription and are believed to be required for normal transcription of several other loci. We have ... [more]
