Phenotypic Enhancement
A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.
Publication
Chromatin assembly factor Asf1p-dependent occupancy of the SAS histone acetyltransferase complex at the silent mating-type locus HMLalpha.
Transcriptional repression of the silent mating-type loci HMLalpha and HMRa in Saccharomyces cerevisiae is regulated by chromatin structure. Sas2p is a catalytic subunit of the SAS histone acetyltransferase (HAT) complex. Although many HATs seem to relieve chromosomal repression to facilitate transcriptional activation, sas mutant phenotypes include loss of SIR1-dependent silencing of HMLalpha. To gain insight into the mechanism of the ... [more]
