SMT3

SUMO family protein SMT3, L000001938, YDR510W
Ubiquitin-like protein of the SUMO family; conjugated to lysine residues of target proteins; associates with transcriptionally active genes; regulates chromatid cohesion, chromosome segregation, APC-mediated proteolysis, DNA replication and septin ring dynamics; phosphorylated at Ser2

DIA2

YOR29-31, DNA-binding SCF ubiquitin ligase subunit DIA2, YOR080W
Origin-binding F-box protein; forms SCF ubiquitin ligase complex with Skp1p and Cdc53p; functions in ubiquitylation of silent chromatin structural protein Sir4p; required to target Cdc6p for destruction during G1 phase; required for deactivation of Rad53 checkpoint kinase, completion of DNA replication during recovery from DNA damage, assembly of RSC complex, RSC-mediated transcription regulation, and nucleosome positioning; involved in invasive and pseudohyphal growth

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Like ubiquitin, the small ubiquitin-related modifier (SUMO) proteins can form oligomeric "chains," but the biological functions of these superstructures are not well understood. Here, we created mutant yeast strains unable to synthesize SUMO chains (smt3(allR)) and subjected them to high-content microscopic screening, synthetic genetic array (SGA) analysis, and high-density transcript profiling to perform the first global analysis of SUMO chain ...

Ontology Terms

  • phenotype: colony size (APO:0000063)

Additional Notes

  • SGA analysis; decreased colony size; smt3allR allele, in which all nine lysine codons have been mutated to code for arginine; the resulting polypeptide can be conjugated to proteins as a monomer, but does not form SUMO chains.
