RAD18

E3 ubiquitin-protein ligase RAD18, L000001567, YCR066W
E3 ubiquitin ligase; forms heterodimer with Rad6p to monoubiquitinate PCNA-K164; heterodimer binds single-stranded DNA and has single-stranded DNA dependent ATPase activity; required for postreplication repair; SUMO-targeted ubiquitin ligase (STUbl) that contains a SUMO-interacting motif (SIM) which stimulates its ubiquitin ligase activity towards the sumoylated form of PCNA

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.

Publication

The RAD6/BRE1 histone modification pathway in Saccharomyces confers radiation resistance through a RAD51-dependent process that is independent of RAD18.

Game JC, Williamson MS, Spicakova T, Brown JM

We examine ionizing radiation (IR) sensitivity and epistasis relationships of several Saccharomyces mutants affecting post-translational modifications of histones H2B and H3. Mutants bre1Delta, lge1Delta, and rtf1Delta, defective in histone H2B lysine 123 ubiquitination, show IR sensitivity equivalent to that of the dot1Delta mutant that we reported on earlier, consistent with published findings that Dot1p requires H2B K123 ubiquitination to fully ...
