Increased protein synthesis, an obligatory step in cell proliferation, is regulated by the phosphorylation of a number of translational components, such as ribosomal protein S6.  p70 S6 Kinase (p70 [S6K]), a cytosolic kinase that is primarily responsible for S6 phosphorylation, belongs to a family of at least six S6 kinases.  p70 [S6K] and p85 [S6K] are two isoforms of the same kinase.  Although they are encoded by the same gene, p80 [S6K] contains a 23 amino acid N-terminal extension that serves as a nuclear localization sequence.  These kinases are located in a p21 ras-independent signaling pathway and are regulated by Ser/Thr phosphorylation in response to mitogenic stimulation.  Activation of p70 [S6K] requires sequential phosphorylations within the autoinhibitory domain and at Thr 389.  p70 [S6K] associates with PDK-1 and PKCζ to form a possible PI3-K signaling complex.  The immunosuppressive agent rapamycin forms an intracellular complex with FKBP12 and FRAP (RAFT1) that inhibits phosphorylation of p70 [S6K] at Thr 389 and, in turn, prevents enzyme activation.  Thus, p70 [S6K] is an important regulator of cell proliferation and a potential target of agents that modify the immune and proliferative responses.  p70 [S6K] has been reported to be observable migrating within a range of 60-70 kD by western blotting.

Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
