CTK1

cyclin-dependent serine/threonine protein kinase CTK1, L000000432, YKL139W
Catalytic (alpha) subunit of C-terminal domain kinase I (CTDK-I); phosphorylates both RNA pol II subunit Rpo21p to affect transcription and pre-mRNA 3' end processing, and ribosomal protein Rps2p to increase translational fidelity; required for H3K36 trimethylation but not dimethylation by Set2p; similar to the Drosophila dCDK12 and human CDK12 and probably CDK13
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)

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.

Involvement of yeast carboxy-terminal domain kinase I (CTDK-I) in transcription elongation in vivo.

Jona G, Wittschieben BO, Svejstrup JQ, Gileadi O

Yeast cells lacking transcription elongation factor genes such as PPR2 (TFIIS) and ELP (Elongator) are viable and show deleterious phenotypes only when transcription is rendered less effective by RNA polymerase mutations or by decreasing nucleotide pools. Here we demonstrate that deletion of the CTK1 gene, encoding the kinase subunit of RNA polymerase II carboxy-terminal domain kinase I (CTDK-I), is synthetically ... [more]
