Protein Classification

F-box protein( domain architecture ID 1903342)

F-box protein functions as the substrate-recognition component of an SCF (Skp1-Cullin-F-box protein) ubiquitin-protein ligase that is involved in ubiquitin-dependent degradation

93-128 4.68e-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.

93-128 4.68e-04

F-box domain found in F-box only protein 28 (FBXO28) and similar proteins; FBXO28, also called FBX28, is part of an SCF (SKP1-cullin-F-box) protein ligase complex. It probably recognizes and binds to some phosphorylated proteins and promotes their ubiquitination and degradation. It promotes mitotic progression and regulates topoisomerase IIalpha-dependent DNA decatenation. FBXO28 plays a crucial role in the pathogenesis of the 1q41q42 microdeletion syndrome. 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.
