Gene Information

General description

p70 S6 kinase or p70S6K is a protein that belongs to Ser/Thr protein kinase family. It has a crucial role in cell growth and G1 cell cycle progression. It also has a pivotal role in phosphorylating eEF2k at a conserved serine residue and hence regulating the protein synthesis. Rabbit anti-phospho-(p70S6K) antibody can identify p70 S6 kinase and p85 S6 kinase when phosphorylated at (Thr389). Anti-phospho-S6-kinase (pThr389) antibody reacts specifically with p70 S6 kinase of rat, mouse and human. This product can also detect few phosphorylated isoforms of Protein Kinase C when present at high level in cells.


A synthetic phospho-(Thr389) peptide corresponding to residues around (Thr389) of human p70 S6 kinase, coupled to KLH.


Anti-phospho-S6-kinase (pThr389) antibody can be used in western blotting (chemiluminescent) (diluted 1:1000) using serum-treated NIH3T3 cell extract or insulin-treated HeLa, COS, and C6 cell extracts.

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

The activation of p70s6k is accompanied by a complex series of phosphorylation events. In this review we propose a model of activation which divides p70s6k into four functional modules that cooperate in leading to full enzyme activity. In the light...

Platelet-derived growth factor receptor (PDGF-R) phosphorylation at tyrosines 740/751 and insulin receptor phosphorylation of insulin receptor substrate-1 effects the recruitment and activation of phosphatidylinositol-3-OH kinase (PI(3)K). Changes in PI(3)K activity correlate with cell growth but its downstream signal transducers are...

Elongation factor 2 kinase (eEF2k) phosphorylates and inactivates eEF2. Insulin induces dephosphorylation of eEF2 and inactivation of eEF2 kinase, and these effects are blocked by rapamycin, which inhibits the mammalian target of rapamycin, mTOR. However, the signalling mechanisms underlying these...

We have shown that inhibition of mTOR in granulosa cells and ovarian follicles results in compromised granulosa proliferation and reduced follicle growth. Further analysis here using spontaneously immortalized rat granulosa cells has revealed that mTOR pathway activity is enhanced during...

Growth factors activating the ErbB receptors have been described in prostate tumors. The androgen dependent prostate cancer cell line, LNCaP, expresses the ErbB-1, ErbB-2 and ErbB-3 receptor tyrosine kinases. Previously, it was demonstrated that NRG activates ErbB-2/ErbB-3 heterodimers to induce...
