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.

It is required for the inactivation of zip1 via ubiquitination. This subfamily also includes Saccharomyces cerevisiae methionine-requiring protein 30 (ScMET30, also called E3 ubiquitin ligase complex SCF(Met30) subunit MET30), Aspergillus niger sulfur controller B (AnSCONB, also called sulfur metabolite repression control protein B) and Neurospora crassa sulfur controller 2 (NcSCON2, also called sulfur metabolite repression control protein 2). ScMET30 acts as a transcriptional inhibitor that negatively regulates the expression of sulfur amino acid biosynthesis genes. It controls cell cycle function (being required for the G1/S transition and M-phase but not the S-phase), sulfur metabolism, and methionine biosynthesis as part of the E3 ubiquitin ligase complex SCF(Met30). AnSCONB and NcSCON2 are components of the SCF (sconB/scon-2) E3 ubiquitin ligase complexes involved in the regulation of sulfur metabolite repression, probably by mediating the inactivation or degradation of the metR transcription factor.

F-box domain found in Drosophila melanogaster S-phase kinase-associated protein 2 (DmSKP2) and similar proteins; DmSKP2 is a Drosophila F-box protein that regulates cell proliferation by targeting Dacapo (Dap) for ubiquitination and proteasome-mediated degradation. It plays a role in maintaining diploidy of mitotic cells during development. 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.

F-box domain found in the early mitotic inhibitor (EMI) family of F-box proteins; The EMI family includes FBX5 (EMI1) and FBX43 (EMI2), which are anaphase-promoting complex/cyclosome (APC/C) inhibitors that bind APC/C-CCD20 (Cell division cycle protein 20) and/or APC/C-CDH1 (CDC20 homologue 1) complexes. 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.
