UBR5 C2768S mutation abrogated the interaction with Snail. (IMAGE)
Caption
(A) His pull-down assays showed the abolished interactions between Snail and the UBR5 C2768S. A schematic representation of the UBR5 wild-type and C2768S mutation.
(B) Co-immunoprecipitation assay showed that the interaction between the Snail and the UBR5 C2768S mutation was eliminated. HEK293T cells were transfected with UBR5-Myc, UBR5 C2768S-Myc, and Snail-Flag as indicated. Cell lysates were immunoprecipitated with either anti-Myc or anti-Flag antibodies and immunoblotted with anti-Snail and anti-UBR5 antibodies.
(C) UBR5 C2768S abolished the UBR5-mediated degradation of Snail. HEK293T cells were transfected with Snail-Flag, UBR5-Myc, and UBR5 C2768S-Myc as indicated. Cell lysates were subjected to western blotting analysis with anti-Snail and anti-GFP antibodies.
(D) UBR5 C2768S did not accelerate Snail protein turnover. HEK293T cells were transfected with Snail-Flag, UBR5-Myc, and UBR5 C2768S-Myc and treated with cycloheximide (CHX) as indicated. Cell lysates were subjected to western blotting analysis with anti-Snail and anti-GFP antibodi.
