General description
MSK2 (mitogen- and stress-activated protein kinase-2) is a member of the serine/threonine kinase family that contains two non-identical kinase catalytic domains. MSK2 is also known as ribosomal protein S6 kinase polypeptide 4 (RPS6KA4), that is activated by the mitogen-activated protein kinases- extracellular signal-regulated kinases 1 and 2 (ERK1 and -2) and p38.
Biochem/physiol Actions
MSK2 (mitogen- and stress-activated protein kinase-2) phosphorylates various substrates like cyclic AMP-responsive element-binding protein 1 (CREB1) and the proto-oncogene c-fos. It is a histone-modifying enzyme and a mitogenic factor. The protein is involved in the G1-phase of the cell cycle and has a role in apoptosis. It also modulates the functions of various transcription factors.
