F-box protein

From Wikidoc - Reading time: 2 min

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. F-box motifs commonly exist in proteins in concert with other protein-protein interaction motifs such as leucine-rich repeats and WD repeats.[1]

F-box proteins have also been associated with cellular functions such as signal transduction and regulation of the cell cycle.[2] In plants, many F-box proteins are represented in gene networks broadly regulated by microRNA-mediated gene silencing via RNA interference.[3]
