Ubiquitin-dependent proteolysis of cyclin D1 is associated with normal and tumour cell proliferation and survival. The best characterised member of this family is the SCF FBXO31 (Skp1-Cul1-Rbx1-FBXO31) ubiquitin ligase complex mediates genotoxic stress-induced cyclin D1 degradation [1]. FBXO31 possesses a unique substrate-binding beta barrel domain, whereas cyclin D1 binds to FBXO31 by tucking its free C-terminal carboxylate tail into an open cavity of the C-terminal FBXO31 beta-barrel. Biophysical and functional studies demonstrated that SCFFBXO31 is capable of recruiting and ubiquitinating cyclin D1 in a phosphorylation-independent manner.	Domain
