Controllable multivalent LYTACs enhance targeted protein degradation.
Summary
We developed a DNA-based framework to control the structure of LYTACs (lysosome-targeting chimeras) for enhanced cellular degradation. This method improves the efficiency of targeted protein removal via lysosomal pathways.
Area of Science:
- Biochemistry
- Molecular Biology
- Nanotechnology
Background:
- Lysosome-targeting chimeras (LYTACs) are engineered molecules for targeted protein degradation.
- Controlling LYTAC structure is crucial for optimizing their degradation efficiency.
- Existing methods lack precise control over LYTAC valency and ligand spacing.
Purpose of the Study:
- To develop a versatile DNA-based LYTAC framework.
- To enable precise control over chimera valency and ligand distance.
- To investigate the impact of multivalent LYTACs on degradation efficiency.
Main Methods:
- Utilized DNA self-assembly for constructing LYTAC frameworks.
- Engineered LYTACs with varying valencies (1, 3, and 9).
- Evaluated degradation capabilities across different receptor-mediated pathways.
Main Results:
- Demonstrated precise control over LYTAC valency and ligand spacing using DNA self-assembly.
- Confirmed a multivalent enhancement effect in lysosome-targeting receptor-mediated degradation.
- Showcased broad applicability across various degradation pathways.
Conclusions:
- The DNA-based LYTAC framework offers versatile control over chimera architecture.
- Multivalency significantly enhances LYTAC degradation efficiency.
- This approach provides valuable insights for designing improved LYTACs for targeted protein degradation.

Regulated Protein Degradation
7.1K
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.

The Proteasome
813
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...

Covalently 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.

Targeted Cancer Therapies
7.5K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Protein Complexes with Interchangeable Parts
2.5K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.

The Proteasome Structure
697
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.
