F-box domain found in Arabidopsis thaliana F-box/LRR-repeat protein 13 (AtARP13), 25 (AtARP25) and similar proteins
AtARP13 and AtARP25 belong to the largest subfamily of plant F-box proteins, F-box/LRR-repeat protein (FBLs). It contains tandem leucine-rich repeats (LRRs). Like other F-box proteins, they may be components of SCF (Skp1 Cdc53 F-box protein) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target 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.
Feature 1:putative Skp1 binding site [polypeptide binding site]
Evidence:
Comment:based on the structure evidences that other F-box superfamily members interact with Skp1
Comment:F-box proteins participate in SCF (Skp1-Cul1-F-box protein) complexes that function as ubiquitin E3 ligases, where the role of the F-box protein is to recruit target substrates.
