Ring finger protein 168

This gene encodes an E3 ubiquitin ligase protein that contains a RING finger, a motif present in a variety of functionally distinct proteins and known to be involved in protein-DNA and protein-protein interactions. The protein is involved in DNA double-strand break (DSB) repair. Mutations in this gene result in Riddle syndrome. [provided by RefSeq, Sep 2011] (from NCBI)

Histone H1 couples initiation and amplification of ubiquitin signalling after DNA damage.
Mailand et al., Copenhagen, Denmark. In Nature, Dec 2015
This depends on the sequential actions of the E3 ubiquitin ligases RNF8 and RNF168 (refs 1-6), and UBC13 (also known as UBE2N), an E2 ubiquitin-conjugating enzyme that specifically generates K63-linked ubiquitin chains.
MAD2L2 controls DNA repair at telomeres and DNA breaks by inhibiting 5' end resection.
Jacobs et al., Amsterdam, Netherlands. In Nature, Jun 2015
These activities of MAD2L2 depend on ATM kinase activity, RNF8, RNF168, 53BP1 and RIF1, but not on PTIP, REV1 and REV3, the latter two acting with MAD2L2 in translesion synthesis.
REV7 counteracts DNA double-strand break resection and affects PARP inhibition.
Rottenberg et al., Amsterdam, Netherlands. In Nature, Jun 2015
REV7 is recruited to DSBs in a manner dependent on the H2AX-MDC1-RNF8-RNF168-53BP1 chromatin pathway, and seems to block HR and promote end joining in addition to its regulatory role in DNA damage tolerance.
Ataxia telangiectasia: more variation at clinical and cellular levels.
Byrd et al., Birmingham, United Kingdom. In Clin Genet, Mar 2015
There is also locus heterogeneity because mutation of the MRE11 gene can cause an obvious A-T like disorder both clinically and also at the cellular level and mutation of the RNF168 gene results in a much milder clinical phenotype, neurologically, with the major clinical feature being an immunological defect.

In particular, the DSB response critically relies on active ubiquitination by the RNF8 and RNF168 ub ligases at the chromatin, which is essential for proper DSB signaling and repair.

RNF168 ubiquitinates K13-15 on H2A/H2AX to drive DNA damage signaling.
Sixma et al., Amsterdam, Netherlands. In Cell, 2012
Ubiquitin-dependent signaling during the DNA damage response (DDR) to double-strand breaks is initiated by two E3 ligases, RNF8 and RNF168, targeting histone H2A and H2AX. Study shows that ubiquitin chains per se are insufficient for signaling, but RNF168 target ubiquitination is required for DDR.

Glover et al., Edmonton, Canada. In J Biol Chem, 2012
Data show RING finger (RNF) E3 ubiquitin ligase RNF8 dimerizes and binds to E2 ubiquitin-conjugating complex Ubc13/Mms2 with formation of Lys-63 ubiquitin chains, whereas the RNF168 RING domain is a monomer and does not catalyze Lys-6 ubiquitylation.

Inactivation of K13 and K15 reduces RNF168- dependent ubiquitination of histones H2As, while inactivation of both N- and C-terminal sites completely abolishes histone ubiquitination.
Close encounters of the RNF8th kind: when chromatin meets DNA repair.
van Attikum et al., Leiden, Netherlands. In Curr Opin Cell Biol, 2012
Emerging evidence suggests that the histone ubiquitin ligases RNF8/RNF168 act in concert with ATP-dependent chromatin remodelling enzymes to orchestrate the signalling and repair of DNA lesions in specific chromatin topologies.
