| Gene Variant Descriptions | FBXW7 L443F lies within WD repeat 2 of the Fbxw7 protein (UniProt.org). L443F induces degradation of Mcl-1 and Braf similar to wild-type Fbxw7 in culture but fails to induce Cyclin E degradation (PMID: 32907612), results in a loss of NICD degradation leading to increased Notch transcriptional activity in a reporter assay (PMID: 27247421), and decreased binding, ubiquitination, and degradation of Mlst8 in culture (PMID: 34741373). |
