HTA1

H2A1, SPT11, histone H2A, L000000827, YDR225W
Histone H2A; core histone protein required for chromatin assembly and chromosome function; one of two nearly identical subtypes (see also HTA2); DNA damage-dependent phosphorylation by Mec1p facilitates DNA repair; acetylated by Nat4p; N-terminally propionylated in vivo

TOM1

E3 ubiquitin-protein ligase TOM1, L000002983, YDR457W
E3 ubiquitin ligase of the hect-domain class; has a role in mRNA export from the nucleus and may regulate transcriptional coactivators; involved in degradation of excess histones; interacts with Dia2p and is required for Dia2p degradation; required to target Cdc6p for ubiquitin-mediated destruction during G1 phase
Saccharomyces cerevisiae (S288c)

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.

Alterations in DNA replication and histone levels promote histone gene amplification in Saccharomyces cerevisiae.

Libuda DE, Winston F

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.
