10098484 However, the MEK inhibitor PD98059 was not able to modulate phosphorylation of CREB at a dose that fully inhibited the phosphorylation of MAP kinase (Fig. 6b ).
10951185 (CellType: dendritic) This could occur via RSK2, a protein kinase activated by MAP kinases/ERKs, that phosphorylates CREB on its activator site serine 133 [ 43 ].
