RNF8

The protein encoded by this gene contains a RING finger motif and an FHA domain. This protein has been shown to interact with several class II ubiquitin-conjugating enzymes (E2), including UBE2E1/UBCH6, UBE2E2, and UBE2E3, and may act as an ubiquitin ligase (E3) in the ubiquitination of certain nuclear proteins. This protein is also known to play a role in the DNA damage response and depletion of this protein causes cell growth inhibition and cell cycle arrest. Alternative splicing results in multiple transcript variants.

Interaction

Homodimer. Forms a E2-E3 ubiquitin ligase complex composed of the RNF8 homodimer and a E2 heterodimer of UBE2N and UBE2V2. Interacts with class III E2s, including UBE2E1, UBE2E2, and UBE2E3 and with UBE2N. Interacts with RXRA. Interacts (via FHA domain) with ATM-phosphorylated MDC1. Interacts (via FHA domain) with 'Thr-4827' phosphorylated HERC2 (via C-terminus). Interacts with PIWIL1; leading to sequester RNF8 in the cytoplasm (By similarity). Interacts with WRAP53/TCAB1 (PubMed:25512560). (Microbial infection) Interacts (via FHA domain) with phosphorylated human herpesvirus 1 ICP0 protein; leading to RNF8 degradation by the proteasome.
