F-box domain found in Arabidopsis thaliana F-box/WD-40 repeat-containing protein 1 (AtFBW1) and similar proteins; AtFBW1, also called WD-40-associated F-box protein 1, is an F-box protein that contains four WD-40 repeats, which are separated from each other by a spacer region. Like other F-box proteins, AtFBW1 may be a component of SCF (Skp1 Cdc53 F-box protein) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins. This subfamily also contains many F-box only proteins that do not have any WD repeat. 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. : Pssm-ID: 438928 Cd Length: 39 Bit Score: 69.80 E-value: 1.34e-15

Most examples are found C-terminal to an F-box (pfam00646), a 60 amino acid motif involved in ubiquitination of target proteins to mark them for degradation. Two-hybid experiments support the idea that most members are interchangeable F-box subunits of SCF E3 complexes. Some members have two copies of this domain.

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. Pssm-ID: 438852 Cd Length: 35 Bit Score: 45.51 E-value: 5.35e-07

F-box domain found in Arabidopsis thaliana F-box protein GID2 and similar proteins; AtGID2, also called protein SLEEPY 1, is an essential component of the SCF-type E3 ligase complex, SCF(GID2), a complex that positively regulates the gibberellin signaling pathway.

F-box domain found in Schizosaccharomyces pombe Skp1-binding protein 1 (SpPof1) and similar proteins; SpPof1, also called F-box/WD repeat-containing protein pof1, probably recognizes and binds to some phosphorylated proteins and promotes their ubiquitination and degradation. 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. 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 F-box associated (FBA) family of F-box proteins; The F-box associated (FBA) family is composed of FBXO2, FBXO6, FBXO17, FBXO27, and FBXO44, which contain a conserved G domain that mediates substrate binding. Members of this family play diverse roles in glycoprotein quality control. They bind high mannose and sulfated glycoproteins, with one FBA protein, FBXO44, failing to bind any glycans on the tested arrays. FBA proteins are components of canonical SCF (Skp1, Cullin1, and Rbx1) complexes, yet FBXO2 bound very little Cullin1, suggesting that FBXO2 may exist primarily as a heterodimer with Skp1. 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 F-box only proteins FBXO6, FBXO44 and similar proteins; This subfamily includes FBXO6 and FBXO44. FBXO6, also called FBX6, F-box protein that recognizes sugar chains 2 (FBS2), or F-box/G-domain protein 2 (FBG2), is a substrate-recognition component of SCF (SKP1-CUL1-F-box protein)-type E3 ubiquitin ligase complexes. It is involved in the endoplasmic reticulum-associated degradation pathway (ERAD) for misfolded lumenal proteins, by recognizing and binding sugar chains on unfolded glycoproteins that are retro-translocated into the cytosol and promoting their ubiquitination and subsequent degradation. FBXO6 can recognize and bind denatured glycoproteins, which are modified with not only high-mannose but also complex-type oligosaccharides. It also recognizes sulfated glycans. FBXO6 is involved in DNA damage response by specifically recognizing activated CHEK1 (phosphorylated on 'Ser-345'), promoting its ubiquitination and degradation. FBXO44, also called FBXO6A, FBX44, or F-box/G-domain protein 3 (FBG3), is a substrate-recognition component of an SCF-type E3 ubiquitin ligase complex. It interacts with SKP1 and CUL1. FBXO44 mediates BRCA1 ubiquitination and degradation. 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.
