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

Yeast SAS silencing genes and human genes associated with AML and HIV-1 Tat interactions are homologous with acetyltransferases.

Reifsnyder C, Lowell J, Clarke A, Pillus L

Silencing is an epigenetic form of transcriptional regulation whereby genes are heritably, but not necessarily permanently, inactivated. We have identified the Saccharomyces cerevisiae genes SAS2 and SAS3 through a screen for enhancers of sir1 epigenetic silencing defects. SAS2, SAS3 and a Schizosaccharomyces pombe homologue are closely related to several human genes, including one associated with acute myeloid leukaemia arising from ... [more]
