GemC1 interacts with Idas but does not interact with Cdt1. U2OS cells were co-transfected with vectors expressing GemC1-HA and Idas-GFP or Cdt1-GFP, as indicated. For each lane, following immunoprecipitation with anti-HA specific antibodies, total cell lysates and immunoprecipitates were analyzed by Western blotting with anti-GFP (upper panel) and anti-HA (lower panel) specific antibodies. In the lower panel, the grey star marks the large chain of the IgGs present in the anti-HA immunoprecipitates. The unlabelled bands in the upper panel are nonspecific bands for the weak interaction of GPA with Idas-GFP, but no interaction with Cdt1-GFP is detected. |
