AB  - <jats:title>Abstract</jats:title><jats:p>Ribosomal S6 Kinases (S6Ks) are critical regulators of cell growth, homeostasis, and survival, with dysregulation of these kinases being associated with various malignancies. While S6K1 has been extensively studied, S6K2 has been neglected despite its reported involvement in cancer progression. Protein arginine methylation is a widespread post-translational modification regulating a plethora of biological responses in mammalian cells. Here we report that p54-S6K2 is asymmetrically dimethylated at Arg-475 and Arg-477, two conserved residues within the AT-hook motif of the S6K2 family and some AT-hook-containing proteins. We demonstrate that PRMT1, PRMT3, and PRMT6 bind to and methylate S6K2<jats:italic>in vitro</jats:italic>and<jats:italic>in vivo</jats:italic>. This methylation localises S6K2 to the nucleus where it rescues cells from starvation-induced cell death. Taken together, our findings highlight a novel mechanism regulating the biological function of p54-S6K2 that may be relevant to cancer where Arg-methylation is often found elevated.</jats:p>
