Summary
The target of rapamycin complex 2 (TORC2), a cell growth regulator, is activated by direct ribosome association. This mechanism may link TORC2 activity to the cell's growth capacity.
Area of Science:
- Cellular Biology
- Molecular Biology
- Biochemistry
Background:
- The target of rapamycin complex 2 (TORC2) is a crucial kinase complex regulating cell growth and survival.
- Understanding the upstream activators of TORC2 is essential for deciphering its role in cellular homeostasis.
Discussion:
- This study presents evidence for the direct activation of TORC2 through its physical association with ribosomes.
- This interaction suggests a novel mechanism for coordinating TORC2 signaling with protein synthesis and cellular growth rates.
Key Insights:
- Direct ribosome binding activates TORC2.
- This activation links TORC2 function to the cell's translational capacity and intrinsic growth potential.
Outlook:
- Further investigation into the precise molecular details of TORC2-ribosome interaction is warranted.
- This finding opens new avenues for exploring TORC2's role in diseases characterized by altered cell growth, such as cancer.

Ribosomes
Ribosomes translate genetic information encoded by messenger RNA (mRNA) into proteins. Both prokaryotic and eukaryotic cells have ribosomes. Cells that synthesize large quantities of protein—such as secretory cells in the human pancreas—can contain millions of ribosomes.
Ribosome Structure and Assembly
Ribosomes are composed of ribosomal RNA (rRNA) and proteins. In eukaryotes, rRNA is transcribed from genes in the nucleolus—a part of the nucleus that specializes in ribosome production. Within...

Cells Coordinate Growth and Proliferation
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...
mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

PI3K/mTOR/AKT Signaling Pathway
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...
