Protein function

Phosphorylates specifically ribosomal protein S6. / ATP + a protein = ADP + a phosphoprotein.

Protein sequence and domain

Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. S6 kinase subfamily. / Contains 1 AGC-kinase C-terminal domain. / Contains 1 protein kinase domain.

Protein post-translational modifications

Phosphorylated and activated by MTOR. Phosphorylation by PKC within the NLS in response to mitogenic stimuli causes cytoplasmic retention.

Protein cellular localization
