چکیده انگلیسی
The cell uses specialised Y-family DNA polymerases or damage avoidance mechanisms to replicate past damaged sites in DNA. These processes are under complex regulatory systems, which employ different types of post-translational modification. All the Y-family polymerases have ubiquitin binding domains that bind to mono-ubiquitinated PCNA to effect the switching from replicative to Y-family polymerase. Ubiquitination and de-ubiquitination of PCNA are tightly regulated. There is also evidence for another as yet unidentified ubiquitinated protein being involved in recruitment of Y-family polymerases to chromatin. Poly-ubiquitination of PCNA stimulates damage avoidance, and, at least in yeast, PCNA is SUMOylated to prevent unwanted recombination events at the replication fork. The Y-family polymerases themselves can be ubiquitinated and, in the case of DNA polymerase η, this results in the polymerase being excluded from chromatin.
