== Function == | |||
[https://www.uniprot.org/uniprot/RN111_HUMAN RN111_HUMAN] Acts in the NODAL pathway of mesoderm patterning during embryonic development. Acts downstream AXIN1 as an E3 ubiquitin-protein ligase which promotes the ubiquitination of inhibitory SMADs such as SMAD7, induces their proteasomal degradation and thereby enhances the transcriptional activity of TGF-beta and BMP. Activates Smad3/Smad4-dependent transcription by triggering signal-induced SnoN degradation. Associates with UBE2D2 as an E2 enzyme.<ref>PMID:14657019</ref> <ref>PMID:16601693</ref> <ref>PMID:17591695</ref> <ref>PMID:22411132</ref> | |||

== Publication Abstract from PubMed == | |||
Arkadia (Rnf111), an E3 Ubiquitin (Ub) ligase, amplifies TGF-beta signaling responses by targeting for degradation of the negative regulators Smad6/7 and the SnoN/Ski transcriptional repressors when they block the TGF-beta 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 (beta)betabetaalpha 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. (c) 2012 Wiley Periodicals, Inc. | |||
