Summary
Ubiquitin modifies key proteins controlling cell functions like cycle progression and DNA repair. Aberrations in these ubiquitin-regulated nodes are common in cancer, suggesting therapeutic potential.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Ubiquitin plays a critical role in regulating essential biological processes.
- Dysregulation of ubiquitin-modified proteins is implicated in cancer development.
- Identifying these key proteins is crucial for understanding oncogenesis.
Purpose of the Study:
- To define key proteins regulated by ubiquitin in biological functions.
- To examine oncogenic alterations of these ubiquitin-modified proteins.
- To explore the therapeutic potential of targeting these molecular hubs in cancer.
Main Methods:
- Literature review and analysis of existing data on ubiquitin modification.
- Identification and categorization of key-node proteins.
- Discussion of oncogenic aberrations and potential therapeutic strategies.
Main Results:
- Ubiquitin regulates diverse cellular functions, including cell cycle, apoptosis, proliferation, and DNA damage response.
- Key proteins involved in these functions are targets of ubiquitin modification.
- Aberrant modifications of these key-node proteins are frequently observed in oncogenesis.
Conclusions:
- Ubiquitin-regulated key-node proteins are central to cancer biology.

Covalently Linked Protein Regulators
Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein.

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...
Regulated Protein Degradation
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Protein Networks
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
