Sequence statusComplete.
Protein existenceEvidence at protein level.

General annotation (Comments)

Function

Phosphorylates 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.

Catalytic activity

ATP + a protein = ADP + a phosphoprotein.

Subunit structure

Interacts with TUSC4. Ref.14

Subcellular location

Cytoplasm. Membrane; Peripheral membrane protein. Note: Membrane-associated after cell stimulation leading to its translocation. Tyrosine phosphorylation seems to occur only at the plasma membrane.

Tissue specificity

Appears to be expressed ubiquitously.

Post-translational modification

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. Ref.6 Ref.8 Ref.10 Ref.11 Ref.12 Ref.13 Ref.15 Ref.16 Ref.17 Ref.19

Sequence similarities

Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. PDK1 subfamily.

Contains 1 PH domain.

Contains 1 protein kinase domain.

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: O15530-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: O15530-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-50: Missing.
Isoform 3 (identifier: O15530-3)

The sequence of this isoform differs from the canonical sequence as follows:
     238-263: Missing.
