Surprising Protein Movement Seen In Cells

ement of the proteins inside the cell.

The Golgi apparatus processes and packages molecules needed for a multitude of functions. The biologists were surprised to discover that the proteins move fast enough to traverse the organelle within a few seconds. At that speed, they should easily be taken up by vesicles and transported outside of the Golgi apparatus.

"How Golgi membranes maintain their identity amidst this rapid diffusion of resident components now needs to be explained," said the senior author of the paper, Jennifer Lippincott-Schwartz, from the National Institutes of Health.

Other biologists involved in the work were Nelson B. Cole and Carolyn Smith of NIH, Mark Terasaki from the University of Connecticut and Noah Sciaky from the National Jewish Center for Immunology and Respiratory Medicine.
