FBXW2(redirected from FBW2)
FBXW2A gene on chromosome 9q34 that encodes a so-called F-box protein, which contains a 40 amino acid protein-interacting motif (the F box). F- box proteins form a complex with SKP1 and cullin, resulting in phosphorylation-dependent ubiquitination. F-box proteins are divided into three classes based on the presence of:
(1) WD-40 repeat—as is the case with this F-box protein (Fbws class);
(2) leucine-rich repeats (Fbls class); or
(3) the presence or absence of other protein-protein-interacting domains (Fbxs class).
