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

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

Publication

Crosstalk between SUMO and ubiquitin on PCNA is mediated by recruitment of the helicase Srs2p.

Papouli E, Chen S, Davies AA, Huttner D, Krejci L, Sung P, Ulrich HD

Posttranslational modification of proliferating cell nuclear antigen (PCNA), an essential processivity clamp for DNA polymerases, by ubiquitin and SUMO contributes to the coordination of DNA replication, damage tolerance, and mutagenesis. Whereas ubiquitination in response to DNA damage promotes the bypass of replication-blocking lesions, sumoylation during S phase is damage independent. As both modifiers target the same site on PCNA, an ... [more]
