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

POL30

proliferating cell nuclear antigen, PCNA, L000001463, YBR088C
Proliferating cell nuclear antigen (PCNA); functions as the sliding clamp for DNA polymerase delta; may function as a docking site for other proteins required for mitotic and meiotic chromosomal DNA replication and for DNA repair

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.

Constitutive fusion of ubiquitin to PCNA provides DNA damage tolerance independent of translesion polymerase activities.

Pastushok L, Hanna M, Xiao W

In response to replication-blocking DNA lesions, proliferating cell nuclear antigen (PCNA) can be conjugated with a single ubiquitin (Ub) or Lys63-linked Ub chains at the Lys164 residue, leading to two modes of DNA damage tolerance (DDT), namely translesion synthesis (TLS) and error-free DDT, respectively. Several reports suggest a model whereby monoubiquitylated PCNA recruits TLS polymerases through an enhanced physical association. ... [more]
