MSK1, a mitogen and stress activated protein kinase, is activated by Erk as well as p38 MAPK in response to growth factors and cellular stress (1).
MSK1 resembles RSK by having two kinase domains connected by a regulatory linker region (2).
Phosphorylation of RSK1 at Ser364 and Ser381 is critical for RSK1 activity (3).
These sites are analogous to Ser360 and Ser376 of MSK1, which may be important for MSK1 activity as well.
Recommended Dilution: Western Blotting: 1:1000 Immunohistochemistry (Paraffin): 1:50
Optimal dilutions to be determined by the researcher.
Storage and Stability: May be stored at 4°C for short-term only.
For long-term storage, store at -20°C.
Aliquots are stable for at least 12 months at -20°C.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Further dilutions can be made in assay buffer.
