RNF8 is an E3 ubiquitin ligase that, through its FHA domain, binds MDC1 phosphorylated at T-Q-X-F (Thr-Gln-X-Phe) sites by ATM. The phosphorylation of at least four T-Q-X-F sites of MDC1 (T699, T719, T752, T765) increases RNF8 binding to MDC1 (Kolas et al. 2007). RNF8 functions as a homodimer formed by interactions of the RNF8 coiled-coil domains (Cambell et al. 2012).
