Amino acids bind to phase-separating proteins and modulate biomolecular condensate stability and dynamics.

Summary: Inside our cells, there are tiny, jelly-like blobs called condensates that help the cell do its important jobs. For a long time, scientists didn't fully understand how the basic building blocks of our bodies—called amino acids—affected these blobs. Now, researchers have discovered that amino acids, like glycine, can actually soak into these blobs and change how they act. They make the blobs looser, less dense, and more jiggly. This exciting discovery gives scientists a brand-new way to control how these important cell parts work in the future!
