WebAug 1, 2024 · In this study, we identified USP38 as a DUB that positively controls c-Myc expression. USP38 is able to enhance the stability of c-Myc by antagonizing the function of FBW7α. Importantly, USP38 regulates cell proliferation through c-Myc. Thus, USP38 plays an important role in the regulation of c-Myc function. WebOct 26, 2004 · This was further demonstrated by fusion of the Fbw7α-specific exon to full-length Fbw7γ, which redistributed Fbw7γ from a nucleolar to a nucleoplasmic pattern (panel N-α +Fbw7γ in Figure 1E). Although we found that BD1 functions as the sole Fbw7γ NLS, none of the basic regions specifically affected nucleolar targeting ( Figure 1E and data ...

WebTo identify the domains of Fbw7 involved in its interaction with KLF5, full-length Fbw7α, Fbw7αΔF, and the WD40 domain were FLAG-tagged and coexpressed with GFP-KLF5. Fbw7α or its mutants were precipitated using anti-FLAG antibody, and copurified KLF5 was detected using anti-GFP antibody (Fig. 3B). Both Fbw7αΔF and the WD40 domain alone ... WebFurthermore, overexpression of either Fbw7α or GSK3β was sufficient to down-regulate endogenous Runx2 expression and function; however, both failed to inhibit endogenous Runx2 when either of them was depleted in osteoblasts. Fbw7α-mediated inhibition of Runx2 expression also led to reduced Runx2 transactivation and osteoblast differentiation.
