Webb2 juni 2024 · Ribosomal S6 kinase (RSK) is the main kinase inducing YB-1 phosphorylation. Meanwhile, phosphorylation of YB-1 at S102, which is necessary for the majority of YB-1 functions, depends on the activity of ribosomal protein S6 kinase. LJI308 is a potent RSK inhibitor. The IC 50 s are 6 nM, 4 nM, and 13 nM for RSK1, RSK2, and RSK3, respectively.
