Overview

Ribosomal protein S6 kinase alpha-6 (RPS6KA6) is a constitutively active serine/threonine-protein kinase belonging to the ribosomal S6 kinase family, with growth-factor-independent kinase activity. It has been implicated in regulation of cell proliferation and may participate in p53/TP53-dependent signaling pathways related to tumor suppression, although its exact roles appear distinct from other RSK family members. This protein is expressed in multiple tissues and may act as a negative regulator of cellular growth pathways, including possible regulation of the ERK1/2 MAP kinase cascade[1][4][7][8].
