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)

DST1

PPR2, SII, S-II, TFIIS, P37, L000001476, L000000530, YGL043W
General transcription elongation factor TFIIS; enables RNA polymerase II to read through blocks to elongation by stimulating cleavage of nascent transcripts stalled at transcription arrest sites; maintains RNAPII elongation activity on ribosomal protein genes during conditions of transcriptional stress
Saccharomyces cerevisiae (S288c)

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

Cleavage, but not read-through, stimulation activity is responsible for three biologic functions of transcription elongation factor S-II.

Ubukata T, Shimizu T, Adachi N, Sekimizu K, Nakanishi T

Transcription elongation factor S-II stimulates cleavage of nascent transcripts generated by RNA polymerase II stalled at transcription arrest sites. In vitro experiments have shown that this action promotes RNA polymerase II to read through these transcription arrest sites. This S-II-mediated cleavage is thought to be necessary, but not sufficient, to promote read-through in the in vitro systems. Therefore, Saccharomyces cerevisiae ... [more]
