Summaries for RNF43 Gene

Entrez Gene Summary for RNF43 Gene

  • The protein encoded by this gene is a RING-type E3 ubiquitin ligase and is predicted to contain a transmembrane domain, a protease-associated domain, an ectodomain, and a cytoplasmic RING domain. This protein is thought to negatively regulate Wnt signaling, and expression of this gene results in an increase in ubiquitination of frizzled receptors, an alteration in their subcellular distribution, resulting in reduced surface levels of these receptors. Mutations in this gene have been reported in multiple tumor cells, including colorectal and endometrial cancers. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2015]

GeneCards Summary for RNF43 Gene

RNF43 (Ring Finger Protein 43) is a Protein Coding gene. Diseases associated with RNF43 include Sessile Serrated Polyposis Cancer Syndrome and Hyperplastic Polyposis Syndrome. Among its related pathways are HIV Life Cycle and Signaling by Wnt. Gene Ontology (GO) annotations related to this gene include ligase activity and obsolete signal transducer activity. An important paralog of this gene is ZNRF3.

UniProtKB/Swiss-Prot for RNF43 Gene

  • E3 ubiquitin-protein ligase that acts as a negative regulator of the Wnt signaling pathway by mediating the ubiquitination, endocytosis and subsequent degradation of Wnt receptor complex components Frizzled. Acts on both canonical and non-canonical Wnt signaling pathway. Acts as a tumor suppressor in the intestinal stem cell zone by inhibiting the Wnt signaling pathway, thereby resticting the size of the intestinal stem cell zone.

  • Sessile serrated polyposis cancer syndrome (SSPCS) [MIM:617108]: A rare disease characterized by multiple and/or large serrated polyps developing in the colon, and an increased personal and familial risk of colorectal cancer. A patient is diagnosed with SSPCS if at least one of the following criteria is met: the presence of at least five sessile serrated polyps proximal to the sigmoid colon, two of which are greater than 10 mm in diameter; the presence of any number of serrated polyps occurring proximal to the sigmoid colon in an individual who has a first-degree relative with serrated polyposis; the presence of more than 20 serrated polyps of any size distributed throughout the colon. Sessile serrated polyps are also known as sessile serrated adenomas (SSA) and are estimated to be responsible for 20 to 35% of all colon cancers. Individuals with SSPCS may have a strong personal or family history of extracolonic cancers. {ECO:0000269 PubMed:24512911, ECO:0000269 PubMed:27081527}. Note=Disease susceptibility may be associated with variations affecting the gene represented in this entry.
