| Description | This entry represents the RING-type zinc finger domain of E3 ubiquitin-protein ligase RNF43. Proteins containing this domain are found in vertebrates.RNF43 acts as a negative regulator of the Wnt signaling pathway by mediating the ubiquitination and subsequent degradation of Wnt receptor complex components Frizzled and LRP6 [ , , ]. RNF43 also interacts with NEDD-4-like ubiquitin-protein ligase-1 (NEDL1) and regulates p53-mediated transcription []. It may also be involved in cell growth control potentially through the interaction with, a chromatin-associated protein interfacing the nuclear envelope []. Mutations of RNF43 have been identified in various tumours, including colorectal cancer (CRC), endometrial cancer, mucinous ovarian tumours, gastric adenocarcinoma, pancreatic ductal adenocarcinoma, liver fluke-associated cholangiocarcinoma, hepatocellular carcinoma, and glioma [, , ]. RNF43 contains an N-terminal signal peptide, a protease-associated (PA) domain, a transmembrane (TM) domain and a C3H2C3-type RING-H2 finger domain followed by a long C-terminal region [].In frogs (Xenopus), ZNRF3 and RNF43 were seen to play a key role in limb specification, constituting a master switch along with RSPO2, which may have implications for regenerative medicine [ ]. | Name | E3 ubiquitin-protein ligase RNF43, Zinc finger, RING-type |
