Role of a crucial protein helps answer why the cell’s transportation hub looks like a stack of pancakes Researchers have pinpointed a protein that keeps the trains running through the cell’s Grand Central station. The protein works in tandem with other molecules to pull membrane packets off the surface of a cell’s Golgi apparatus, giving the crucial organelle its distinctive flattened shape. “It’s a nice simple mechanism for how the shape of something is a consequence of its function,” says Seth Field of the University of California, San Diego and a coauthor of the study, which appears in the Oct....
