Summary
Deubiquitinating enzymes (DUBs) regulate cellular signaling pathways crucial for cancer. Understanding DUBs
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Ubiquitination regulates critical cellular signaling pathways.
- Dysregulation of cellular signaling is fundamental to cancer development, progression, and metastasis.
- Deubiquitinating enzymes (DUBs) oppose the action of E3 ubiquitin ligases, collectively controlling ubiquitin signaling.
Purpose of the Study:
- To explore the multifaceted roles of DUBs in cancer physiology.
- To highlight the complex and context-dependent involvement of DUBs in cancer hallmarks.
- To underscore the potential of DUBs as therapeutic targets in oncology.
Main Methods:
- Review of existing literature on DUBs and cancer.
- Analysis of DUB involvement in various cancer signaling pathways.
- Examination of DUBs' impact on cancer hallmarks.
Main Results:
- DUBs are implicated in all hallmarks of cancer.
- Individual DUBs can influence multiple cancer pathways, exhibiting both pro- and anti-cancer activities.
- The balance between ubiquitination and deubiquitination is critical for proteostasis and cellular responses.
Conclusions:
- DUBs play complex, context-dependent roles in cancer.
- Further research into DUB function will identify specific DUBs for targeted inhibition or activation.
- Targeting DUBs holds promise for developing novel cancer therapies and identifying patient populations.

01:13The Proteasome
855
Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

02:58Regulated Protein Degradation
7.3K
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.

02:04Covalently Linked Protein Regulators
6.8K
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.

2.1K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...

00:50Anaphase Promoting Complex
2.9K
The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...

01:17The Proteasome Structure
773
The ubiquitin-proteasome pathway is a well-known mechanism utilized by eukaryotic cells to remove cytoplasmic proteins that are misfolded, damaged, or no longer needed. In this pathway, the protein that needs to be eliminated undergoes a process called ubiquitination, where a chain of ubiquitin molecules is attached to the 48th lysine residue of the target protein. This ubiquitin modification helps the proteasome distinguish between a target protein and a healthy protein.
