| Background | F-box only protein 31 is a ~60 kDa protein. Substrate-recognition component of the SCF(FBXO31) protein ligase complex, which specifically mediates the ubiquitination of proteins amidated at their C-terminus in response to oxidative stress, leading to their degradation by the proteasome. FBXO31 specifically recognizes and binds C-terminal peptides bearing an amide: C-terminal amidation in response to oxidative stress takes place following protein fragmentation. The SCF(FBXO31) also plays a role in G1 arrest following DNA damage by mediating ubiquitination of phosphorylated cyclin-D1 (CCND1), promoting its degradation by the proteasome, resulting in G1 arrest. The SCF(FBXO31) complex is however not a major regulator of CCND1 stability during the G1/S transition. In response to genotoxic stress, the SCF(FBXO31) complex directs ubiquitination and degradation of phosphorylated MDM2, thereby promoting p53/TP53-mediated DNA damage response. 1. Muhar, MF. et al.
