3-Phosphoinositide-dependent protein kinase-1 (PDK1) is a serine/threonine protein kinase known to phosphorylate and activate PKB/AKT (Thr308 and Ser473), p70 S6 kinase, RSK, PKA, PKC and SGK. Upon stimulation of receptor tyrosine kinases, PI3K becomes activated and generates the phospholipid second messengers, PtdIns(3,4,5)P 3 and PtdIns(3,4)P 2.,which in turn mediate the phosphorylation and activation of PDK1 targets through diverse mechanisms (1-2). It has also been shown that stimulation of cells with pervanadate and IGF-1 results in a significant increase in PDK1 activity and translocation to the plasma membrane along with an increase in tyrosine phosphorylation (3). Only phosphorylation on the activation loop at Ser241 is necessary for PDK1s activity and a single nucleotide mutation abolishes its activity (4).
Suitable for use in Western Blot, Immunohistochemistry. Other applications not tested.
Western Blot: 1:1000
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
