NCBI Protein Information
3'-phosphoinositide-dependent protein kinase 1
NCBI Summary
Encodes 3-phosphoinositide-dependent protein kinase that contains pleckstrin homology domain and binds 3-phosphoinositides. It activates the protein kinase AGC2-1 in a phosphatidic acid dependent manner. Phosphorylates S6K1. Interacts with PID, and transphosphorylation by PDK1 increases PID autophosphorylation.

UniProt Comments
May couple lipid signals to the activation-loop phosphorylation of several protein kinases of the so-called AGC kinase family. Interacts via its pleckstrin homology domain with phosphatidic acid, PtdIns3P and PtdIns(3,4)P2 and to a lesser extent with PtdIns(4,5)P2 and PtdIns4P. May play a general role in signaling processes controlling the pathogen/stress response, polar auxin transport and development. Transphosphorylates the AGC protein kinases OXI1/AGC2-1, PK1/S6K1, PK19/S6K2 and PID resulting in their activation.
