LEU3
leucine-responsive transcriptional regulator LEU3, L000000944, YLR451W
Zinc-knuckle transcription factor, repressor and activator; regulates genes involved in branched chain amino acid biosynthesis and ammonia assimilation; acts as a repressor in leucine-replete conditions and as an activator in the presence of alpha-isopropylmalate, an intermediate in leucine biosynthesis that accumulates during leucine starvation

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.
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.
