This PDF file includes:

  • Materials and Methods
  • Fig. S1. AKTi-1/2 inhibits AKT activity in HEK293 and BJ-T cells.
  • Fig. S2. AKTi-1/2 represses rDNA transcription and rRNA processing.
  • Fig. S3. Knockout of AKT isoforms reduces rDNA transcription.
  • Fig. S4. Overexpression of MyrAKT3 increases cell size and serum starvation induces cell cycle arrest without changing apoptosis rates.
  • Fig. S5. Knockdown of raptor mimics the effect of rapamycin on RNA Pol I loading.
  • Fig. S6. Overexpression of MyrAKT3 increases the abundance of the ribosomal subunits 40S, 60S, and 80S.
  • Fig. S7. AKT does not modulate c-MYC abundance or activity and c-MYC does not modulate AKT abundance.
