DYRK

In (e), quiescent cells were left untreated or treated for 30 min with 10 nM R1881, in the absence or presence of the DYRK 1B inhibitor AZ191, which was added (1 μM) 15 min before hormonal stimulation. Control cells in right panel were treated with the inhibitor alone. In left panels, lysate proteins were immunoprecipitated with anti-DYRK 1B antibody. Immune complexes were analyzed for DYRK 1B activity using MBP as a substrate. DYRK 1B levels in immune complexes were detected by immunoblot with anti-DYRK 1B antibody. In right panels, lysate proteins were analyzed by western blot, using antibodies against the indicated proteins.
