The interior of a cell from a moving protein's point of view

Numerous obstacles posed by cellular structures hinder protein movements within the cell. Researchers now have succeeded in mapping the intracellular topology by observing proteins in living cells on multiple time and length scales. By developing a new fluorescence microscopy-based technique, the researchers were able to measure how long it takes proteins to move over distances ranging from 0.2 to 3 micrometres in living cells.
