General description

Ribosomal protein S6 kinase α-1 (RPS6KA1) or RSK1 is a member of the RSK (ribosomal S6 kinase) family that consists of growth factor-regulated serine/threonine kinases. RSK1 contains 2 nonidentical kinase catalytic domains. RSK1 encodes a predicted 735-amino acid protein containing 2 distinct consensus ATP-binding site sequences. RSK1 transcript is present in lymphocytes, skeletal muscle, liver, and adipose tissue.

Biochem/physiol Actions

Ribosomal S6 kinases (RSKs) are implicated in the activation of the mitogen-activated kinase (MAPK) cascade and the stimulation of cell proliferation and differentiation. The protein suppresses the pro-apoptotic function of BAD by phosphorylating it. RSK1 phosphorylates various substrates, including members of the mitogen-activated kinase (MAPK) signaling pathway.

Physical form

Supplied in 50 mM Tris-HCl, pH 7.5, with 150 mM NaCl, 0.2 5mM DTT, 0.1 mM EGTA, 0.1 mM EDTA, 0.1 mM PMSF, and 25% glycerol.
