  • Function
    Serine/threonine-protein kinase that acts downstream of ERK (MAPK1/ERK2 and MAPK3/ERK1) signaling and mediates mitogenic and stress-induced activation of transcription factors, regulates translation, and mediates cellular proliferation, survival, and differentiation. May function as tumor suppressor in epithelial ovarian cancer cells.
  • Tissue specificity
    Widely expressed with higher expression in lung, skeletal muscle, brain, uterus, ovary, thyroid and prostate.
  • Sequence similarities
    Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily.
    Contains 1 AGC-kinase C-terminal domain.
    Contains 2 protein kinase domains.
  • Post-translational
    Activated by phosphorylation at Ser-218 by PDPK1. Autophosphorylated on Ser-377, as part of the activation process. May be phosphorylated at Thr-356 and Ser-360 by MAPK1/ERK2 and MAPK3/ERK1.
    N-terminal myristoylation results in an activated kinase in the absence of added growth factors.
