    Arkadia (Rnf111), an E3 Ubiquitin (Ub) ligase, amplifies TGF-β signaling responses by targeting for degradation of the negative regulators Smad6/7 and the SnoN/Ski transcriptional repressors when they block the TGF-β effectors Smad2/3. The E3 ligase activity of Arkadia depends on its C-terminal RING-H2 domain that constitutes the docking site for the E2 Ub-conjugating enzyme carrying the activated Ub. We determined the nuclear magnetic resonance solution structure of Arkadia's RING-H2 domain and revealed a (β)ββα fold, fully consistent with the expected "cross-brace" mode of Zn(II)-ligation. In addition, the interaction of the Arkadia RING-H2 domain with its E2 partner enzyme (UbcH5b) was examined through chemical shift perturbation. Proteins 2012. © 2012 Wiley Periodicals, Inc.
