Summary

Reversible protein highlighting is a light-based live-cell imaging assay that uses a photochromic fluorescent protein to repeatedly highlight, erase, and re-highlight labeled molecules without destructive readout. It was applied to visualize stimulus-dependent, bidirectional nucleocytoplasmic shuttling of extracellular signal-regulated kinase (ERK) across the nuclear envelope.

Usefulness & Problems

Why this is useful

This method is useful for directly observing regulated protein movement in living cells when repeated marking of the same labeled population is required. The cited study specifically used it to monitor fast signaling-associated nucleocytoplasmic transport of ERK.

Source:

Because of its photochromic properties, the protein could be highlighted, erased, and highlighted again in a nondestructive manner, allowing direct observation of regulated fast nucleocytoplasmic shuttling of key signaling molecules.

Problem solved

It addresses the problem of visualizing rapid, regulated, bidirectional trafficking of signaling proteins across the nuclear envelope in a nondestructive manner. The evidence specifically supports its use for stimulus-dependent ERK shuttling.
