Publication Abstract from PubMedGenetically encoded fusion constructs derived from fluorescent proteins (FPs) can be designed to report on a multitude of events and signals in cells, tissues, and entire organs without interfering with the complex machinery of life.

This property enables localized tagging of proteins and thus provides a valuable tool for tracking protein movements within live cells.
