Summary
Viral proteases that remove ubiquitin are crucial for herpesvirus infection and spread. Understanding these deconjugases offers insights into viral biology and potential roles in cancer development.
Area of Science:
- Biochemistry
- Virology
- Molecular Biology
Background:
- Ubiquitin modification regulates key cellular and viral processes, including virus infection and replication.
- Herpesviruses utilize ubiquitin pathways, with all known members encoding proteases targeting ubiquitin conjugates.
- These viral proteases, termed deconjugases, are essential for viral life cycle progression.
Purpose of the Study:
- To investigate the role of viral deconjugases in herpesvirus biology.
- To structurally and functionally characterize these viral enzymes.
- To identify the viral and cellular substrates of deconjugases and explore their implications in malignant transformation.
Main Methods:
- Structural and functional characterization of viral deconjugases.
- Identification of viral and cellular protein substrates.
- Analysis of deconjugase activity in viral infection and replication.
Main Results:
- Herpesvirus deconjugases specifically recognize and cleave ubiquitin conjugates.
- Characterization provides insights into the mechanism of viral deconjugase action.
- Substrate identification reveals deconjugase involvement in viral pathogenesis.
Conclusions:
- Viral deconjugases are critical regulators of the herpesvirus life cycle.
- These enzymes are potential targets for antiviral therapies.
- Emerging evidence links deconjugases to cellular transformation and cancer.

01:32Export of Misfolded Proteins out of the ER
4.1K
After folding, the ER assesses the quality of secretory and membrane proteins. The correctly folded proteins are cleared by the calnexin cycle for transport to their final destination, while misfolded proteins are held back in the ER lumen. The ER chaperones attempt to unfold and refold the misfolded proteins but sometimes fail to achieve the correct native conformation. Such terminally misfolded proteins are then exported to the cytosol by ER-associated degradation or ERAD pathway for...

01:13The Proteasome
1.2K
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
7.9K
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.

01:38Intralumenal Vesicles and Multivesicular Bodies
3.9K
Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...

02:04Covalently Linked Protein Regulators
7.8K
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.

01:15Receptor Downregulation in MVBs
2.3K
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.
