Fig. XX.2. GST pull-down experiments.
Individual HA-tagged Akt isoforms were expressed in HEK-293T mammalian cells. Expressed proteins were incubated with GST or GST-POSH, and then GST pull-down assays were carried out. The bound proteins were washed and subjected to immunoblot analysis with anti-HA (A) and anti-GST (B, C) antibodies.
