Background:
- Ubiquitin-conjugating enzymes (E2s) are crucial for regulating oncogenic signaling pathways.
- E2s control protein stability, localization, and interactions, impacting cancer hallmarks like proliferation and metastasis.
Purpose of the Study:
- To systematically review E2-mediated signaling mechanisms in various cancer types.
- To propose translational strategies for targeting E2 enzymes therapeutically.
Main Methods:
- Literature review of E2-mediated signaling in cancer.
- Analysis of E2 roles in cancer hallmarks.
- Identification of therapeutic opportunities for E2-targeted interventions.
Main Results:
- E2s orchestrate diverse ubiquitin chain topologies that drive cancer progression.
- E2s are implicated in key oncogenic processes including proliferation, immune evasion, metastasis, and metabolic reprogramming.
- E2s represent an underexplored class of therapeutic targets in oncology.
Conclusions:
- Targeting E2 enzymes offers a promising therapeutic avenue for cancer treatment.
- Further research into E2-mediated signaling can unlock novel anti-cancer strategies.
- Translational approaches are needed to exploit E2s for clinical benefit.

02:04Covalently Linked Protein Regulators
9.9K
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
9.3K
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.

01:13The Proteasome
2.0K
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...

00:50Anaphase Promoting Complex
3.5K
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...

3.0K
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.
