1-28 1.96e-08

F-box domain superfamily; This short domain is commonly found at the N-terminus of various proteins, and typically co-occurs with one or more other conserved domains or motifs, such as leucine rich repeats, WD40 repeats, kelch, tub, spry, and others. The F-box domain has a role in mediating protein-protein interactions in a variety of contexts, such as polyubiquitination, transcription elongation, centromere binding and translational repression. One of the best researched roles of F-box proteins is their participation in SCF (Skp1-Cul1-F-box protein), a multi-protein complex that functions as a ubiquitin E3 ligase, where the role of the F-box protein is to recruit target substrates. Gene families containing the F-box are found greatly expanded in narrow taxonomic lineages, such as flowering plants and nematodes. In this hierarchical classification, many of the subfamilies are named according to their domain architectures.

1-28 1.96e-08

F-box domain found in F-box only protein 21 (FBXO21) and similar proteins; FBXO21, also called FBX21, is the substrate-recognition component of an SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complex. It facilitates Lys29-linkage and activation of ASK1 (apoptosis signal-regulating kinase 1) and promotes type I interferon production upon viral infection. It also polyubiquitylates EP300-interacting inhibitor of differentiation 1 (EID1) and is required for the efficient degradation of EID1 in both cycling and quiescent cells. The F-box domain has a role in mediating protein-protein interactions in a variety of contexts, such as polyubiquitination, transcription elongation, centromere binding and translational repression.
