Description

General description

S6 kinase (p70s6k) is activated by an upstream kinase, mTOR in response to nutrients and growth factors. S6 kinase (p70s6k) is a critical regulatory component and mTOR along with the eukaryotic initiation factor 4E (eIF4E)–binding protein 1 (4E-BP1) and S6 kinase (p70s6k) leads to increased ribosomal biogenesis and hence translation. As a critical component and has the ability to modify the cellular responses to availability of nutrients, and growth factors like insulin and IGF-1 when mTOR is chronically active. In presence of excess and chronic insulin, or high fat diets, S6 kinase (p70s6k) regulates by a negative feedback loop and constitutively shuts down the responsiveness of cells to insulin. Thus, mTOR through the S6 kinase (p70s6k) plays a pivotal role in the development of insulin resistance and type 2 diabetes. mTOR signaling via p70S6 kinase also drives cell growth and proliferation, cancer and aging.
Anti-phospho-S6-kinase (p70S6K) (phosphothreonine 421/phosphoserine424) detects p70 S6 kinase and p85 S6 kinase only when activated by phosphorylation at Thr421/Ser424 and does not cross-react with other phosphoylated protein kinases.

Immunogen

synthetic double phospho-Thr⁴²¹/Ser⁴²⁴ peptide corresponding to residues around Thr⁴²¹/Ser⁴²⁴ of human p70^S6K.

Application

Anti-phospho-S6-kinase (p70S6K) may be used for immunoblotting at a working dilution of 1:1000 in serum-treated NIH-3T3 cells. For immunoprecipitation, the recommended dilultion is 1:250.

Biochem/physiol Actions

Does not react with non-phosphorylated S6 kinase (p70^S6K) or other phosphorylated protein kinases.

Physical form

Solution in 10 mM sodium HEPES, pH 7.5, containing 150 mM sodium chloride, 100 μg/ml bovine serum albumin and 50% glycerol
