Webb1 juni 2006 · Of all of the ribosomal proteins, rpS6 has attracted much attention because it is the first (and for many years was the only) substrate that has been shown to undergo inducible phosphorylation. Notably, phosphorylated rpS6 can be detected in both the cytosol and the nucleus [13]. WebbThe phosphorylation of ribosomal protein S6 (rpS6) has been described for the first time about four decades ago. Since then, numerous studies have shown that this …
