FIGURE 5.
The PH domain of PdkA is dispensable for function. A, pdkA−pdkB− cells expressing vector (V), PdkA-GFP, and PdkAΔPH-GFP were starved on a non-nutrient agar plate and allowed to form fruiting bodies. B, pdkA−pdkB− cells expressing PdkAΔPH-GFP, PdkA(K98R)-GFP, or PdkAΔPH(K98R)-GFP were treated as in A. C, cell extracts from pdkA−pdkB− cells expressing vector (V), PdkA-GFP, and PdkAΔPH-GFP were prepared at the indicated times after 1 μm cAMP stimulation and probed with α-phospho-protein kinase C (pan) antibody (upper panel) and α-GFP antibody (lower panel). D, the levels of AL phosphorylations of PkbR1 and PkbA (upper panel) and the expression of PdkA (lower panel) were compared in cells from B.
