【Abstract】In recent years, people pay more and more attentions to the development of reversibly photoswitchable fluorescent proteins (RSFPs), because those fluorescent proteins can greatly promote the development and application of living-cell super-resolution imaging techniques. Reversibly photoswitchable fluorescent protein can be repeatedly and reversibly modulated by light with different wavelengths, thus it can be widely applied in many fields such as optical storage of high density data, the measurement of photochromic fluorescence resonance energy transfer, and super-resolution imaging based on the principle of reversible saturable optical linear fluorescence transitions (RESOLFT). The recent development of green RSFPs is reviewed from the key amino acids involved in RSFPs design. We also make a brief discussion of the relationship between structure and optical characteristics of RSFPs, serving as the reference for further structure-guided development of better RSFPs.
