e/F-box protein

Information
has gloss	eng: F-box proteins are proteins containing at least one F-box motif, a protein structural motif of about 50 amino acids that mediates protein-protein interactions. The first identified F-box protein is one of three components of the SCF complex, which mediates ubiquitination of proteins targeted for degradation by the proteasome. The F-box motif interacts directly with the SCF protein Skp1 , and F-box motifs commonly exist in proteins in concert with other protein-protein interaction motifs such as leucine-rich repeats and WD repeats, which are thought to mediate interactions with SCF substrates .
