    basic FUNCTION
  • protein kinase inhibition
  • linking Rho GTPases to cytoskeleton reorganization and nuclear signaling
  • playing a role in the regulation of the biochemistry and morphology of the apoptotic cell
  • phosphorylating ribosomal protein S6, histone H4 and myelin basic protein
  • regulates spindle orientation in a CDC42/Rac1 binding-dependent and kinase activity-independent manner
  • cooperate with PAK1, PAK3 kinase, and CHL1, most likely in independent pathways, in regulating morphological development of the leading process/apical dendrite of embryonic cortical neurons
