[[http://www.uniprot.org/uniprot/CTNB1_HUMAN CTNB1_HUMAN]] Defects in CTNNB1 are associated with colorectal cancer (CRC) [MIM:[http://omim.org/entry/114500 114500]]. Note=Activating mutations in CTNNB1 have oncogenic activity resulting in tumor development. Somatic mutations are found in various tumor types, including colon cancers, ovarian and prostate carcinomas, hepatoblastoma (HB), hepatocellular carcinoma (HCC). HBs are malignant embryonal tumors mainly affecting young children in the first three years of life. Defects in CTNNB1 are a cause of pilomatrixoma (PTR) [MIM:[http://omim.org/entry/132600 132600]]; a common benign skin tumor.<ref>PMID:11703283</ref> <ref>PMID:12027456</ref> <ref>PMID:10192393</ref> Defects in CTNNB1 are a cause of medulloblastoma (MDB) [MIM:[http://omim.org/entry/155255 155255]]. MDB is a malignant, invasive embryonal tumor of the cerebellum with a preferential manifestation in children.<ref>PMID:12027456</ref> <ref>PMID:10666372</ref> Defects in CTNNB1 are a cause of susceptibility to ovarian cancer (OC) [MIM:[http://omim.org/entry/167000 167000]]. Ovarian cancer common malignancy originating from ovarian tissue. Although many histologic types of ovarian neoplasms have been described, epithelial ovarian carcinoma is the most common form. Ovarian cancers are often asymptomatic and the recognized signs and symptoms, even of late-stage disease, are vague. Consequently, most patients are diagnosed with advanced disease. Note=A chromosomal aberration involving CTNNB1 is found in salivary gland pleiomorphic adenomas, the most common benign epithelial tumors of the salivary gland. Translocation t(3;8)(p21;q12) with PLAG1. Defects in CTNNB1 may be a cause of mesothelioma malignant (MESOM) [MIM:[http://omim.org/entry/156240 156240]]. An aggressive neoplasm of the serosal lining of the chest. It appears as broad sheets of cells, with some regions containing spindle-shaped, sarcoma-like cells and other regions showing adenomatous patterns. Pleural mesotheliomas have been linked to exposure to asbestos.<ref>PMID:11464291</ref>

[[http://www.uniprot.org/uniprot/FBW1A_HUMAN FBW1A_HUMAN]] Substrate recognition component of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Recognizes and binds to phosphorylated target proteins. SCF(BTRC) mediates the ubiquitination of CTNNB1 and participates in Wnt signaling. SCF(BTRC) mediates the ubiquitination of NFKBIA, NFKBIB and NFKBIE; the degradation frees the associated NFKB1 to translocate into the nucleus and to activate transcription. Ubiquitination of NFKBIA occurs at 'Lys-21' and 'Lys-22'. SCF(BTRC) mediates the ubiquitination of phosphorylated NFKB1/nuclear factor NF-kappa-B p105 subunit, ATF4, SMAD3, SMAD4, CDC25A, DLG1, FBXO5 and probably NFKB2. SCF(BTRC) mediates the ubiquitination of phosphorylated SNAI1. May be involved in ubiquitination and subsequent proteasomal degradation through a DBB1-CUL4 E3 ubiquitin-protein ligase. Required for activation of NFKB-mediated transcription by IL1B, MAP3K14, MAP3K1, IKBKB and TNF. Required for proteolytic processing of GLI3.<ref>PMID:9859996</ref> <ref>PMID:10066435</ref> <ref>PMID:10497169</ref> <ref>PMID:10835356</ref> <ref>PMID:10644755</ref> <ref>PMID:11359933</ref> <ref>PMID:11238952</ref> <ref>PMID:11994270</ref> <ref>PMID:12791267</ref> <ref>PMID:14681206</ref> <ref>PMID:12902344</ref> <ref>PMID:14603323</ref> <ref>PMID:14988407</ref> <ref>PMID:15448698</ref> <ref>PMID:16371461</ref> [[http://www.uniprot.org/uniprot/CTNB1_HUMAN CTNB1_HUMAN]] Key downstream component of the canonical Wnt signaling pathway. In the absence of Wnt, forms a complex with AXIN1, AXIN2, APC, CSNK1A1 and GSK3B that promotes phosphorylation on N-terminal Ser and Thr residues and ubiquitination of CTNNB1 via BTRC and its subsequent degradation by the proteasome. In the presence of Wnt ligand, CTNNB1 is not ubiquitinated and accumulates in the nucleus, where it acts as a coactivator for transcription factors of the TCF/LEF family, leading to activate Wnt responsive genes. Involved in the regulation of cell adhesion. Acts as a negative regulator of centrosome cohesion. Involved in the CDK2/PTPN6/CTNNB1/CEACAM1 pathway of insulin internalization. Blocks anoikis of malignant kidney and intestinal epithelial cells and promotes their anchorage-independent growth by down-regulating DAPK2.<ref>PMID:17524503</ref> <ref>PMID:18086858</ref> <ref>PMID:18957423</ref> <ref>PMID:21262353</ref> [[http://www.uniprot.org/uniprot/SKP1_HUMAN SKP1_HUMAN]] Essential component of the SCF (SKP1-CUL1-F-box protein) ubiquitin ligase complex, which mediates the ubiquitination of proteins involved in cell cycle progression, signal transduction and transcription. In the SCF complex, serves as an adapter that links the F-box protein to CUL1. SCF(BTRC) mediates the ubiquitination of NFKBIA at 'Lys-21' and 'Lys-22'; the degradation frees the associated NFKB1-RELA dimer to translocate into the nucleus and to activate transcription. SCF(Cyclin F) directs ubiquitination of CP110.<ref>PMID:16209941</ref> <ref>PMID:20181953</ref>
