General description
The p70 S6 kinase is a ubiquitous cytoplasmic protein that is activated in response to cytokines, and growth factors including the epidermal growth factor and fibroblast growth factor. It lies downstream of the mTOR/PI3K pathway and is phosphorylated on multiple residues: Thr389, Thr229, Thr421, Ser371, Ser404, Ser411, Ser418, and Ser424. Thr389, Ser371, and Ser404 are located in the linker domain; whereas Thr421, Ser411, Ser418, Ser424 are located in the autoinhibitory domain, and Thr229 is found in the catalytic domain. These sites may be phosphorylated in a hierarchical sequence leading to the activation of the p70 S6 kinase. The p70 S6 kinase phosphorylates the S6 protein on the 40S ribosomal protein (rpS6), and plays a role in multiple processes including regulation of mRNA molecules with 5’-terminal oligopyrimidine tracts, protein synthesis, cell growth, proliferation, and cell survival. The activity of this kinase may be important in diabetes, cancer, and aging.
