MAPKAPK5 (PRAK) forms a complex with MAPK14 (p38 alpha) or MAPK11 (p38 beta) irrespective of the phosphorylation status and kinase activity of MAPKAPK5, MAPK14 and MAPK11 (New et al. 2003). Phosphorylation of p38 alpha and p38 beta by MKK3 or MKK6 (Raingeaud et al. 1996), however, is required for the subsequent activation of MAPKAPK5 by p38 MAPK (New et al. 1998, Sun et al. 2007).
