Recombinant Human RNF43 Protein, mFc Tag

Molecular Characterization: RNF43 (Glu43-Tyr197) mFc (Pro99-Lys330) Molecular weight: The protein has a predicted molecular mass of 39.4 kDa after removal of the signal peptide. The apparent molecular mass of RNF43-mFc is approximately 40-70 kDa due to glycosylation.Description: Recombinant human RNF43 protein with C-terminal mouse Fc tagThe 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.
