  sub:_6 prov:value "The extracellular signal-regulated kinases 1 and 2 (ERK1/2), also known as p44(MAPK) and p42(MAPK), respectively, are two of the kinases associated with HDAC4. ERK1/2 are components of the Ras-mitogen-activated protein kinase (MAPK) signal transduction pathway. Activation of the Ras-MAPK pathway by expression of oncogenic Ras or constitutively active MAPK/ERK kinase 1 results in an increased percentage of cells (from approximately 10% to approximately 70%) that express HDAC4 in the nucleus in C2C12 myoblast cells." ;
