Summary
The FUS protein's low-complexity domain (LCD) forms various assemblies. Murray et al. developed an atomic-level structural model for FUS LCD fibrils, offering new insights into their structure and function.
Area of Science:
- Biochemistry
- Structural Biology
- Molecular Biology
Background:
- The low-complexity domain (LCD) of the FUS protein is known to form concentration-dependent assemblies.
- These assemblies range from liquid droplets to fibril-based hydrogels.
- The precise molecular structures of FUS within these diverse assemblies and their functional implications remain poorly understood and are a subject of ongoing debate.
Purpose of the Study:
- To elucidate the atomic-level structural model of FUS LCD fibrils.
- To provide a deeper understanding of the molecular basis for FUS protein assembly.
- To address existing questions and stimulate further research into the structure-function relationship of FUS assemblies.
Main Methods:
- The study reports the development of an atomic-level structural model for FUS LCD fibrils.
- Specific experimental or computational techniques used for model generation are detailed in the full study.
Main Results:
- An atomic-level structural model for FUS LCD fibrils has been successfully generated.
- This model provides unprecedented detail into the architecture of FUS fibrils.
- The findings offer potential explanations for FUS's assembly behavior and its role in biological processes.
Conclusions:
- The reported atomic-level structural model represents a significant advancement in understanding FUS fibril formation.
- This model answers some long-standing questions regarding FUS LCD fibril structures.
- However, the new structural insights also raise further questions, paving the way for future investigations into FUS proteinopathies and cellular functions.

11.7K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

12.1K
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.

Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.

3.0K
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.

4.8K
Fibrous proteins are either long and narrow proteins or assemble to form long and thin structures. They contain repetitive units and usually consist of either alpha helices or beta sheets and, in rare cases, a mix of both. The amino acids in the primary structure often consist of repeating amino acid sequences. The role of fibrous proteins is primarily structural. Many are located in the extracellular matrix and are present in connective tissues to impart strength and joint mobility. They are...
