"These results indicate that the cul1/skp1/beta-trcp complex forms a ubiquitin ligase that mediates the degradation of beta-catenin."

"TRIM33 ubiquitylates nuclear beta-catenin.|Tumour suppressor TRIM33 targets nuclear beta-catenin degradation."

"Here we show that fwd1 (the mouse homologue of slimb/betatrcp), an f-box/wd40-repeat protein, specifically formed a multi-molecular complex with beta-catenin, axin, gsk-3beta and apc. Mutations at the signal-induced phosphorylation site of beta-catenin inhibited its association with fwd1. Fwd1 facilitated ubiquitination and promoted degradation of beta-catenin, resulting in reduced cytoplasmic beta-catenin levels."

"FOXF2 directly bound the promoter of E3 ligase interferon regulatory factor 2-binding protein-like (IRF2BPL) and induced its transcriptional expression. IRF2BPL in turn interacted with β-catenin, increasing its ubiquitination and degradation."
