MDM33 overexpression suppressor screen
Ontology highlight
ABSTRACT: We performed a genome-wide screen for genetic MDM33 interaction partners. Using the opposite approach of the well known synthetic dosage lethality (screening for deletion strains in which a non-toxic overexpression is associated with a synthetic growth arrest) we screened the whole genome for genes that are essential for the growth arrest associated with MDM33 overexpression. In a pooled collection of viable haploid gene deletion mutants, of which each is tagged with a unique identifying molecular ‘‘bar-code’’ sequence, the overexpression of MDM33 was induced using a galactose responsive promotor. While overexpression resulted in a growth arrest in almost all strains a small fraction of deletion mutants was able to grow under inductive conditions. We identified these strains using a microarray DNA hybridization technique that quantifies the abundance of the molecular barcodes. We propose that the affected genes are possible functional genetic interaction partners of MDM33.
