Also known as p70S6KbP70-BETASTK14BKLSS6KBS6KbetaS6Kβ
Summary
RPS6KB2 (ribosomal protein S6 kinase B2, HGNC:10437) is a protein-coding gene on chromosome 11q13.2, encoding Ribosomal protein S6 kinase beta-2 (Q9UBS0). Phosphorylates specifically ribosomal protein S6.
This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains a kinase catalytic domain and phosphorylates the S6 ribosomal protein and eukaryotic translation initiation factor 4B (eIF4B). Phosphorylation of S6 leads to an increase in protein synthesis and cell proliferation.
