Figure 9. Okadaic acid stimulates ERK5 phosphorylation with different kinetics than palytoxin in 308 cells.

Figure 9

HeLa and 308 cells were incubated for the indicated times with 120 nM okadaic acid. Protein (20 μg) from whole cell lysates was analyzed by immunoblot for the following: ERK5; phosphorylated, active ERK1/2 (pERK1 and pERK2); and total ERK2. The arrow marks the slower migrating form of ERK5. The data shown are representative of at least two independent experiments.
