Our Abpromise guarantee covers the use of ab32800 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/500 - 1/1000. Detects a band of approximately 65 kDa (predicted molecular weight: 63 kDa).
ELISA 1/20000.
IHC-P Use at an assay dependent concentration.
IP Use at an assay dependent concentration.


  • FunctionPhosphorylates and activates not only PKB/AKT, but also PKA, PKC-zeta, RPS6KA1 and RPS6KB1. May play a general role in signaling processes and in development (By similarity). Isoform 3 is catalytically inactive.
  • Tissue specificityAppears to be expressed ubiquitously.
  • Sequence similaritiesBelongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. PDK1 subfamily.
    Contains 1 PH domain.
    Contains 1 protein kinase domain.
  • Post-translational
    Phosphorylated on tyrosine and serine/threonine. Phosphorylation on Ser-241 in the activation loop is required for full activity. PDK1 itself can autophosphorylate Ser-241, leading to its own activation.
  • Cellular localizationCytoplasm. Membrane. Membrane-associated after cell stimulation leading to its translocation. Tyrosine phosphorylation seems to occur only at the plasma membrane.
