Abstract

Green fluorescent protein (GFP) and GFP-like proteins represent invaluable genetically encoded fluorescent probes1,2. In the last few years a new class of photoactivatable fluorescent proteins (PAFPs) capable of pronounced light-induced spectral changes have been developed3. Except for tetrameric KFP1 (ref. 4), all known PAFPs, including PA-GFP5, Kaede6, EosFP7, PS-CFP8, Dronpa9, PA-mRFP110 and KikGR11 require light in the UV-violet spectral region for activation through one-photon excitation - such light can be phototoxic to some biological systems12. Here, we report a monomeric PAFP, Dendra, derived from octocoral Dendronephthya sp. and capable of 1,000- to 4,500-fold photoconversion from green to red fluorescent states in response to either visible blue or UV-violet light. Dendra represents the first PAFP, which is simultaneously monomeric, efficiently matures at 37°C, demonstrates high photostability of the activated state, and can be photoactivated by a common, marginally phototoxic, 488-nm laser line. We demonstrate the suitability of Dendra for protein labeling and tracking to quantitatively study dynamics of fibrillarin and vimentin in mammalian cells.
