LSD6, SAS1, serine/threonine protein kinase CDC7, L000000247, YDL017W
DDK (Dbf4-dependent kinase) catalytic subunit; required for origin firing and replication fork progression in mitotic S phase through phosphorylation of Mcm2-7p complexes and Cdc45p; kinase activity correlates with cyclical DBF4 expression; required for pre-meiotic DNA replication, meiotic DSB formation, recruitment of the monopolin complex to kinetochores during meiosis I and as a gene-specific regulator of the meiosis-specific transcription factor Ndt80p

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.

Persistent Acetylation of Histone H3 Lysine 56 Compromises the Activity of DNA Replication Origins.

Tremblay R, Mehrjoo Y, Ahmed O, Simoneau A, McQuaid ME, Affar EB, Nislow C, Giaever G, Wurtele H

In Saccharomyces cerevisiae, newly synthesized histones H3 are acetylated on lysine 56 (H3 K56ac) by the Rtt109 acetyltransferase prior to their deposition on nascent DNA behind replication forks. Two deacetylases of the sirtuin family, Hst3 and Hst4, remove H3 K56ac from chromatin after S phase. hst3? hst4? cells present constitutive H3 K56ac, which sensitizes cells to replicative stress via unclear ...
