ID:AXIN2_HUMAN DESCRIPTION: RecName: Full=Axin-2; AltName: Full=Axin-like protein; Short=Axil; AltName: Full=Axis inhibition protein 2; AltName: Full=Conductin; FUNCTION: Inhibitor of the Wnt signaling pathway. Down-regulates beta-catenin. Probably facilitate the phosphorylation of beta- catenin and APC by GSK3B (By similarity). SUBUNIT: Interacts with glycogen synthase kinase-3 beta (GSK3B) and beta-catenin. The interaction between axin and beta-catenin occurs via the armadillo repeats contained in beta-catenin (By similarity). Interacts with SMAD7 and RNF111. Interacts with ANKRD6. SUBCELLULAR LOCATION: Cytoplasm. TISSUE SPECIFICITY: Expressed in brain and lymphoblast. DOMAIN: The tankyrase-binding motif (also named TBD) is required for interaction with tankyrase TNKS and TNKS2 (By similarity). PTM: Probably phosphorylated by GSK3B and dephosphorylated by PP2A (By similarity). PTM: ADP-ribosylated by tankyrase TNKS and TNKS2. Poly-ADP- ribosylated protein is recognized by RNF146, followed by ubiquitination and subsequent activation of the Wnt signaling pathway. PTM: Ubiquitinated by RNF146 when poly-ADP-ribosylated, leading to its degradation and subsequent activation of the Wnt signaling pathway. Deubiquitinated by USP34, deubiquitinated downstream of beta-catenin stabilization step: deubiquitination is important Wnt signaling to positively regulate beta-catenin (CTNBB1)-mediated transcription. DISEASE: Defects in AXIN2 are involved in colorectal cancer (CRC) [MIM:114500]. They appear to be specifically associated with defective mismatch repair. DISEASE: Defects in AXIN2 are the cause of oligodontia-colorectal cancer syndrome (ODCRCS) [MIM:608615]. Affected individuals manifest severe tooth agenesis and colorectal cancer or precancerous lesions of variable types. SIMILARITY: Contains 1 DIX domain. SIMILARITY: Contains 1 RGS domain.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
