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.
Physical form
Supplied in 50mM Tris-HCl, pH 7.5, 150mM NaCl, 10mM glutathione, 0.1mM EDTA, 0.25mM DTT, 0.1mM PMSF, 25% glycerol.
Preparation Note
after opening, aliquot into smaller quantities and store at -70 °C. Avoid repeating handling and multiple freeze/thaw cycles

A novel ribosomal S6 kinase (RSK) family member, RSK-B, was identified in a p38alphaMAPK-baited intracellular interaction screen. RSK-B presents two catalytic domains typical for the RSK family. The protein kinase C-like N-terminal and the calcium/calmodulin kinase-like C-terminal domains both contain
