  • FunctionSerine/threonine kinase that may play a role in mediating the growth-factor and stress induced activation of the transcription factor CREB. Essential role in the control of RELA transcriptional activity in response to TNF. Phosphorylates 'Ser-10' of histone H3 in response to mitogenics, stress stimuli and epidemal growth-factor (EGF) and result in the transcriptional activation of several immediate early genes, including proto-oncogenes FOS and JUN (By similarity). Mediates the mitogen- and stress-induced phosphorylation of high mobility group protein 14 (HMG-14).
  • Sequence similaritiesBelongs 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.
