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

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.

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

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 ...

Most drugs target membrane proteins, accessible on the surface of cells, to alter the transport of ions and molecules and the transduction of cellular signals. The Diver lab explores the biological ...

Seed plants, such as soybeans, store large amounts of protein in specialized organelles called protein storage vacuoles.

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 ...

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 ...

Transport across membranes All cells are enclosed by a cell membrane ... of combinations of amino acids. Body proteins include structural proteins, enzymes, hormones and antibodies.
