 6-41 3.83e-11

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.

F-box protein interaction domain; This model describes a large family of plant domains, with several hundred members in Arabidopsis thaliana. 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; This domain is approximately 50 amino acids long, and is usually found in the N-terminal half of a variety of proteins. Two motifs that are commonly found associated with the F-box domain are the leucine rich repeats (LRRs; pfam00560 and pfam07723) and the WD repeat (pfam00400). 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.

 5-38 3.42e-04

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.

F-box domain found in Arabidopsis thaliana protein ATTENUATED FAR-RED RESPONSE (AtAFR) and similar proteins; AtAFR, also called SKP1-interacting partner 29 (AtSKIP29), or F-box protein AFR, is a component of SCF (SKP1/ASK-cullin-F-box protein) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins. It is part of the phyA-mediated signaling transduction pathway leading to the regulation of gene expression and hypocotyl elongation in response to red and far-red light exposure. This subfamily also includes many other Arabidopsis thaliana SKP1-interacting partner proteins. 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 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. Upon gibberellin treatment, the SCF(GID2) complex mediates the ubiquitination and subsequent degradation of DELLA proteins (GAI, RGA and RGL2), some repressors of the gibberellin pathway, leading to the activation of the pathway. 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.

 3-36 5.85e-03

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.
