Caltech Researchers Upend Decades-Old Model of Mitochondrial Protein Import –
Researchers showed that many mitochondrial proteins enter the organelle during synthesis, guided by folding patterns and structural signals. This discovery revises decades of biochemical models. Mitochondria are organelles most commonly known as the “powerhouses of Read More
Fluorescent 'zoom lens' exposes hidden protein changes for earlier disease
A novel strategy developed at Rice University allows scientists to zoom in on tiny segments of proteins inside living cells, revealing localized environmental changes that could indicate the earliest stages of diseases such as Alzheimer’Read More
If you’ve ever accidentally sliced yourself on broken glass or a piece of paper, you may have noticed that the bleeding can be hard to stop. Scientists have long wondered how the cascade of Read More
Imagine tugging on a Chinese finger trap. The harder you pull, the tighter it grips. This counterintuitive behavior also exists in biology. Certain protein complexes can form catch-bonds, tightening their grip when force is applied. Read More
Newly discovered cell machinery breaks down protein aggregates into smaller
A new study from Aarhus University shows that our cells’ ability to clean out old protein clumps, known as aggregates, also includes a—up till now unknown—partnership with an engine that breaks down bigger Read More
Researchers modified a protein in the cell elimination pathway to create a targeted system for destroying disease-causing cells, called Crunch. Summary Researchers engineered a new targeted cell-killing system called “Crunch” by modifying a protein involved Read More
Model plant study reveals how protein clustering impacts gene regulation
Epigenetic silencing governs key biological processes, from flowering time in plants to preventing uncontrolled cell growth that drives cancer in humans. Summary Epigenetic silencing is a crucial biological mechanism that controls essential processes in diverse Read More
Mitochondria are cellular organelles that play an important role in making ATP (adenosine triphosphate), the molecular fuel that powers most cellular functions. These organelles originated over a billion years ago when a primitive archaeal cell Read More
