FBXO42 Proteins and Enzymes

F-box only protein 42 (FBXO42) is a substrate recognition component of the SKP1-CUL1-F-box protein (SCF) type E3 ubiquitin ligase complex. The FBXO42 protein recognizes p53/TP53; which promotes its ubiquitination and degradation. FBXO42 is a member of the F-box protein family. Members of this family are characterized by an approximately 40-amino acid F-box motif. F-box proteins are also known to interact with SKP1 and other ubiquitination targets through their interaction domains.
