Facts about Mitogen-activated protein kinase 4.
Atypical MAPK protein.
Phosphorylates microtubule- associated protein 2 (MAP2) and MAPKAPK5.The precise purpose of the complex formed with MAPKAPK5 is still unclear, but the complex follows a complex set of phosphorylation events: upon interaction with atypical MAPKAPK5, ERK4/MAPK4 is phosphorylated at Ser-186 and then mediates phosphorylation and activation of MAPKAPK5, which in turn phosphorylates ERK4/MAPK4. May promote entry in the cell cycle (By similarity).
