Product details:
70 kDa ribosomal protein S6 kinase (p70S6K or p70S6K beta 1) is a member of a serine/threonine kinase family that phosphorylates the 40S ribosomal protein S6, thereby modulating the translation of ribosomal proteins and translation elongation factors. p70S6K is activated in response to the phosphatidylinositol 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) pathways, and is required for progression through the cell cycle and for cell growth. Activation of p70S6K is regulated by phosphorylation of seven different residues distributed throughout the protein, with the critical sites being threonines 229, 389, 421 and serine 424. Threonine 229 is located within the activation loop.

Properties and Storage Information:
Form-Liquid, Purification technique-Affinity purification Immunogen, Purification notes-Purified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated p70S6K. The final product is generated by affinity chromatography using a p70S6K derived peptide that is phosphorylated at threonine 229., Storage buffer-pH: 7.3Preservative: 0.05% Sodium azideConstituents: PBS, 0.1% BSA, Shipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions--20°C, Aliquoting information-Upon delivery aliquot, Storage information-Avoid freeze / thaw cycle

S6K1 also known as p70S6K is a serine/threonine kinase involved in protein synthesis. The protein has a molecular weight of approximately 70 kDa. Scientists often examine the presence of S6K1 in various tissues as it is expressed ubiquitously in eukaryotic cells. This kinase plays an instrumental role in the regulation of cell growth proliferation and survival by phosphorylating ribosomal protein S6 and other targets. Researchers explore various cellular contexts where S6K1 activity is implicated due to its widespread expression and function.
Biological function summary
S6K1 functions as a downstream effector of the mammalian target of rapamycin (mTOR) complex specifically mTORC1. S6K1 interacts with several protein complexes enhancing its regulatory capacity in cellular activities. It modulates protein synthesis by phosphorylating substrates involved in translation. By controlling these processes S6K1 aids in cell size regulation and energy metabolism which are critical for maintaining cellular homeostasis and adaptation to nutrient availability.
Pathways
S6K1 plays an essential role in the mTOR signaling pathway a central regulator of cell growth and metabolism. S6K1 functions in close connection with proteins such as mTOR and Raptor within this pathway. Additionally it is involved in the insulin signaling pathway where it works with proteins like insulin receptor substrate (IRS). Both pathways highlight S6K1's role in nutrient sensing and response emphasizing its significance in energy and protein homeostasis.
S6K1 is associated with conditions such as cancer and type 2 diabetes. Dysregulation of S6K1 activity can lead to abnormal cell proliferation contributing to oncogenesis in various cancer types. Specifically altered signaling through pathways involving mTOR and Akt proteins connects S6K1 to cancer progression. In type 2 diabetes S6K1 affects insulin sensitivity where overactive S6K1 signaling leads to insulin resistance. Here interactions with insulin receptor substrate proteins highlight its influence on metabolic disorders underlining its critical role in disease pathology.
