Summary
K63 ubiquitination regulates immune signaling, impacting inflammation and pathogen responses. This review explores cellular sensors, pathogen interference (like SARS-CoV-2), and T cell subset control by K63 ubiquitination.
Area of Science:
- Immunology
- Molecular Biology
- Cellular Signaling
Background:
- Ubc13-catalyzed K63 ubiquitination is a critical regulator of immune signaling pathways.
- Dysregulation of K63 ubiquitination affects immune functions, including chronic inflammation, pathogen responses, and lymphocyte activation.
Purpose of the Study:
- To review novel cellular sensors dependent on K63 ubiquitination in immune signaling.
- To detail pathogen strategies targeting K63 ubiquitination, focusing on SARS-CoV-2.
- To discuss the role of K63 ubiquitination in T cell subset regulation (Treg, TH1, TH17).
Main Methods:
- Literature review of recent studies on K63 ubiquitination in immunity.
- Analysis of molecular mechanisms employed by pathogens to manipulate K63 ubiquitination.
- Synthesis of evidence linking K63 ubiquitination to T cell differentiation and function.
Main Results:
- Identification of novel K63 ubiquitination-dependent cellular sensors in immune signaling.
- Elucidation of pathogen mechanisms, including SARS-CoV-2, to evade immune responses via K63 ubiquitination interference.
- Emerging evidence suggests K63 ubiquitination influences the balance between regulatory T cells and T helper subsets.
Conclusions:
- K63 ubiquitination is a central node in immune regulation, targeted by pathogens and involved in T cell fate.
- Understanding these pathways offers insights into chronic inflammation, infectious diseases, and autoimmune disorders.
- Further research is needed to address knowledge gaps and explore clinical applications of K63 ubiquitination modulation.

01:15Receptor Downregulation in MVBs
2.2K
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...

02:04Covalently Linked Protein Regulators
7.7K
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.

02:58Regulated Protein Degradation
7.8K
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.

02:26NF-κB-dependent Signaling Pathway
7.9K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

01:31Regulation of the Unfolded Protein Response
2.6K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

01:20The JAK-STAT Signaling Pathway
9.5K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
