MST4 a S/T protein kinase of the STE20 family. Mst kinases regulate processes such as apoptosis, morphogenesis, and cytoskeletal rearrangements, and are upstream activators of MAPK pathways that. The amino-terminal kinase domain of Mst is considerably homologous to the kinase domain of yeast STE20 kinase and other p21-activated kinases. otential mediator of cell growth. Interaction with Golgi matrix protein GOLGA2 leads to autophosphorylation on Thr-178, possibly as a consequence of stabilization of dimer formation. May also be activated by C-terminal cleavage.
