Bone is not the inert structure we often imagine. It's alive, adapting daily to load-bearing and impact. But with over 200 ...

Intracellular protein trafficking and secretion of proteins into the extracellular environment are sequential and tightly ...

Membrane receptors fall into three major classes: G-protein-coupled receptors, ion channel receptors, and enzyme-linked receptors. The names of these receptor classes refer to the mechanism by ...

These structures do exchange membrane material, however, via a special type of transport. Membranes and their constituent proteins are assembled in the ER. This organelle contains the enzymes ...

Lysosomes are membrane-bound organelles in cells that act as recycling centers—breaking down waste materials, damaged organelles, and unwanted molecules using powerful digestive enzymes.

In neurodegenerative diseases such as Alzheimer's or Parkinson's, proteins accumulate in the body's cells, fold incorrectly ...

Dr. Zhou’s lab focuses on two families of proteins, membrane transport proteins that facilitate transmembrane flux of ions and small molecules, and membrane-embedded enzymes that are involved in ...

Natural enzymes are remarkable molecular machines that enable all sorts of essential biochemical reactions. For decades, ...

In neurodegenerative diseases such as Alzheimer's or Parkinson's, proteins accumulate in the body's cells, fold incorrectly and clump together to form larger aggregates. Normally, cells are able to ...

Approximately 25 percent of proteins localize to membranes, where they act as receptors and signaling molecules in biological processes, including respiration, neurotransmission, and molecular ...

A research team has revealed the molecular steps that led to the emergence of this plant-specific vacuolar transport system. Their work shows that the acquisition of this pathway was driven by the ...

The machinery inserts itself into the cell membrane and a channel forms ... One of these advantageous proteins is an enzyme called exonuclease (ExoN), which helps the virus proofread and correct ...
