UBC13

E2 ubiquitin-conjugating protein UBC13, L000003387, YDR092W
E2 ubiquitin-conjugating enzyme; involved in the error-free DNA postreplication repair pathway; interacts with Mms2p to assemble ubiquitin chains at the Ub Lys-63 residue; DNA damage triggers redistribution from the cytoplasm to the nucleus

SIZ1

ULL1, SUMO ligase SIZ1, S000007589, YDR409W
SUMO/Smt3 ligase; promotes attachment of small ubiquitin-related modifier sumo (Smt3p) to proteins; regulates Rsp5p ubiquitin ligase activity and is in turn itself regulated by Rsp5p; binds Ubc9p and may bind septins; specifically required for sumoylation of septins in vivo; localized to the septin ring; SIZ1 has a paralog, NFI1, that arose from the whole genome duplication

Phenotypic Suppression

A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

The roles of PCNA-SUMOylation, Mms2-Ubc13 and Rad5 in translesion DNA synthesis in Saccharomyces cerevisiae.

Mms2, in concert with Ubc13 and Rad5, is responsible for polyubiquitination of replication processivity factor PCNA. This modification activates recombination-like DNA damage-avoidance mechanisms, which function in an error-free manner. Cells deprived of Mms2, Ubc13 or Rad5 exhibit mutator phenotypes due to the channeling of premutational DNA lesions to often error-prone translesion DNA synthesis (TLS). Here we show that Siz1-mediated PCNA ... [more]

  • Low Throughput

Ontology Terms

  • phenotype: mutation frequency (APO:0000198)

Additional Notes

  • deletion of siz1 also rescues mutation frequency phenotypes in a rad5/mms2, rad5/ubc13 or mms2/ubc13 double mutant
  • mutation of siz1 modulates the mutation frequency increase caused by mutation of ubc13 or rad5
