p70 S6 kinase β also known as S6Kbeta, P70S6Kb, RPS6KB2 is a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. p70 S6 kinase β plays a crucial role in regulating protein synthesis and cell growth, primarily by phosphorylating ribosomal protein S6, which is essential for translating mRNAs that encode proteins involved in cell cycle progression and metabolism. p70 S6 kinase β is activated in response to growth factors and is part of a signaling cascade that includes the ERK MAP kinase family, which is regulated by upstream kinases such as MEK. Precise regulation of p70 S6 kinase β is vital for maintaining cellular homeostasis and responding to external stimuli, making p70 S6 kinase β a significant target for research in cancer and metabolic disorders.
