E3 ubiquitin-protein ligase RAD18 is an enzyme that in humans is encoded by the RAD18 gene. A knockout in a human colorectal cancer cell line, HCT116, has also been created.

Function

The protein encoded by this gene is highly similar to S. cerevisiae DNA damage repair protein Rad18. Yeast Rad18 functions through interaction with Rad6, which is a ubiquitin-conjugating enzyme required for post-replication repair of damaged DNA. Similar to its yeast counterpart, this protein is able to interact with the human homolog of yeast Rad6 protein through a conserved ring finger motif. Mutation of this motif results in defective replication of UV-damaged DNA and hypersensitivity to multiple mutagens.

Interactions

RAD18 has been shown to interact with HLTF, UBE2B and UBE2A.
