Background: MAPKAPK3 / MK3 is part of the classical mammalian mitogen-activated protein kinase (MAPK) pathway and together with MAPKAPK2 /MK2 the major downstream targets of the p38MAPK. Based on structural and functional homology, the MAPKAPKs are divided in four subfamilies: ribosomal S6 kinase (RSK) with the members RSK1-4; mitogen- and stress-activated kinase (MSK) comprising MSK1 and MSK2; MAPK-interacting protein kinase (MNK) including MNK1 and MNK2, and the MAPK-activated protein kinases (MAPKAPK) MK2, MK3 and MK5. MK2, MK3 and MK5 are closely related, but MK2 and MK3 are more identical to each other than to MK5 but MAPKAPK3 kinase activity and level in protein expression are lower compared to MAPKAPK2. MAPKAPK3 is involved in diverse cellular processes, such as reorganization of the cytoskeleton, cell migration, cell-cycle regulation and chromatin remodelling.
