Background: F-box/WD repeat-containing protein 7 is a protein that in humans is encoded by the FBXW7 gene. The F-box proteins constitute one of the four subunits of ubiquitin protein ligase complex called SCFs (SKP1-cullin-F-box), which function in phosphorylation-dependent ubiquitination. Mutations in this gene are detected in ovarian, breast and colorectal cancer cell lines, implicating the gene's potential role in the pathogenesis of human cancers.
Immunogen: A synthetic peptide from the internal region of FBXW7 which includes the mutation of R479L, human origin.
Constituents: PBS (without Mg2+ and Ca2+), pH 7.4, 150 mM NaCl, 50% glycerol
Species Reactivity: Recognizes R479L mutant, but not wild-type FBXW7 of vertebrates.
Storage Conditions: Store at -20°C. Avoid freeze / thaw cycles
Western blot:
Western blot analysis of recombinant FBXW7 (R479L) and wildtype proteins. Purified His-tagged FBXW7 (R479L) protein (lane 2) and corresponding wildtype protein (lane 1) were blotted with anti-FBXW7 (R479L) monoclonal antibody (Cat. #26347).
Immunofluorescence:
Immunofluorescence of cells expressing FBXW7 proteins with anti-FBXW7 (R479L) antibody. HEK293T cells were transfected with pCDNA3-GFP-FBXW7 (WT) plasmid (left column) or pCDNA3-GFP-FBXW7 (R479L) plasmid (right column), then fixed and stained with anti-FBXW7 (R479L) monoclonal antibody (Cat. #26347).
