Background

RNF168 (RING [really interesting new gene] finger protein 168; also E3 ubiquitin-protein ligase RNF168) is a 65 kDa (predicted) member of the RNF168 family of proteins. It is ubiquitously expressed, and serves as an E3 ubiquitin ligase. Following DNA damage, RNF8 is recruited to DNA double-strand breaks by phosphoMDC1. Here, RNF8 first monoubiquitinates histone H2A, and then promotes RNF168 recruitment. RNF168 now acts as an additional ubiquitinase, promoting multiple ubiquitinations plus the recruitment of 53BP1, a scaffold protein that holds DNA damage response elements. Mouse RNF168 is 565 amino acids (aa) in length. It contains one Zn-finger/RING domain (aa 16-55) plus two ubiquitin-interacting MIU motifs (aa 168-191 and 438-461). There are three potential Ser/Thr phosphorylation sites. Two potential isoform variants are reported. One shows an alternative start site at Met20, while a second possesses a two aa extension at the N-terminus coupled to a 13 aa substitution for aa 343-565. Over aa 423-565, mouse RNF168 shares 79% and 65.5% aa sequence identity with rat and human RNF168, respectively. Over aa 423-466, mouse RNF168 shares 98% aa sequence identity with human RNF168.
