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.
