摘要: F-box proteins are the key recognition subunit of multimeric E3 ubiquitin ligase complexes that participate in proteasome degradation specific substrates. In last years, a discrete number have been shown to regulate epithelial-to-mesenchymal transition (EMT), process defined by rapid change cell phenotype, loss epithelial characteristics and acquisition more invasive phenotype. Specific EMT transcription factors (EMT-TFs), such as Snail, Slug, Twist Zeb, control induction both during development cancer. These EMT-TFs short-lived targeted system proteins, keeping them at low levels. also indirectly controlling inducers, Notch, c-Myc or mTOR. Here we summarize role these (Fbxw1, Fbxw7, Fbxl14, Fbxl5, Fbxo11 Fbxo45) play cancer progression, dependent on post-translational modifications govern their interaction with target proteins.
