Putting a finger on plant stress response

Post-translational modification is the process whereby proteins are modified after their initial biosynthesis. Modification can take many forms, including enzymatic cleavage of the protein or the addition of sugars, lipids, ...

Team solves structure of key mTORC1 activator

A research team led by scientists at the Whitehead Institute has described the structure of a key protein complex that helps activate mTORC1, a master growth regulator that enables cells to quickly respond to changing nutrient ...

Researchers create most complete model of complex protein machinery

Environmental conditions, lifestyle choices, chemical exposure, and foodborne and airborne pathogens are among the external factors that can cause disease. In contrast, internal genetic factors can be responsible for the ...

Turning silenced cancer genes back into fighters

Working with human colon cancer cells and mice, researchers led by experts at the Johns Hopkins Kimmel Cancer Center say they have successfully blocked the activity of portions of a protein known as UHRF1 and restored the ...

Proteins use a lock and key system to bind to DNA

You can think of DNA as a string of letters—As, Cs, Ts, and Gs—that together spell out the information needed for the construction and function of cells. Each cell in your body shares the same DNA. So, for cells to take ...
