TOR targets an RNA processing network to regulate facultative heterochromatin, developmental gene expression and cell proliferation.

Project description:Cell proliferation and differentiation require signalling pathways that enforce appropriate and timely gene expression. We find that Tor2, the catalytic subunit of the TORC1 complex in fission yeast, targets a conserved nuclear RNA elimination network, particularly the serine and proline-rich protein Pir1, to control gene expression through RNA decay and facultative heterochromatin assembly. Phosphorylation by Tor2 protects Pir1 from degradation by the ubiquitin-proteasome system involving the polyubiquitin Ubi4 stress-response protein and the Cul4-Ddb1 E3 ligase. This pathway suppresses widespread and untimely gene expression and is critical for sustaining cell proliferation. Moreover, we find that the dynamic nature of Tor2-mediated control of RNA elimination machinery defines gene expression patterns that coordinate fundamental chromosomal events during gametogenesis, such as meiotic double-strand-break formation and chromosome segregation. These findings have important implications for understanding how the TOR signalling pathway reprogrammes gene expression patterns and contributes to diseases such as cancer.

Parallel global profiling of plant TOR dynamics reveals a conserved role for LARP1 in protein translation

Project description:TARGET OF RAPAMYCIN (TOR) is a deeply conserved protein kinase that coordinates eukaryotic metabolism with nutrient availability. In mammals, TOR specifically promotes translation of ribosomal protein mRNAs when amino acids are available to support protein synthesis. The mechanisms controlling translation downstream from TOR remain contested, however, and are largely unexplored in plants. Here, we took parallel global profiling approaches to define the in planta TOR-regulated proteome, and phosphoproteome. We found that TOR regulates ribosome biogenesis in plants at multiple levels. To investigate this further, we focused on a putative TOR substrate identified in our phosphoproteome: LARP1, a eukaryotic RNA-binding protein that is proposed to mediate TOR translational control of 5′TOP mRNAs in humans.
