FKH2
forkhead family transcription factor FKH2, L000002608, YNL068C
Forkhead family transcription factor; plays a major role in the expression of G2/M phase genes; positively regulates transcriptional elongation; facilitates clustering and activation of early-firing replication origins; negative role in chromatin silencing at HML and HMR; substrate of the Cdc28p/Clb5p kinase; relocalizes to the cytosol in response to hypoxia; FKH2 has a paralog, FKH1, that arose from the whole genome duplication

Negative Genetic
Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
Publication
Alterations in DNA replication and histone levels promote histone gene amplification in Saccharomyces cerevisiae.
Gene amplification, a process that increases the copy number of a gene or a genomic region to two or more, is utilized by many organisms in response to environmental stress or decreased levels of a gene product. Our previous studies in Saccharomyces cerevisiae identified the amplification of a histone H2A-H2B gene pair, HTA2-HTB2, in response to the deletion of the ... [more]

Additional Notes
- A synthetic genetic array (SGA) analysis was performed to identify deletions that either increase or decrease/eliminate the viability of an hta1 htb1 double mutant. Since HTA2 -HTB2 gene amplification is required for survival in an hta1 htb1 double mutant background, the level of survival of the triple mutant served as an indicator of the frequency of HTA2-HTB2 amplification.
