The invention provides evolved red-shifted smURFPs. In some embodiments, the smURFPs are characterized by a) increased Fluorescence of smURFP as compared to infrared FPs IFP1.4 and iRFP713; b) expressing efficiently with minimal toxicity; c) does not require a lyase to covalently attach its chromophore, wherein the chromophore is biliverdin; d) exhibit a wavelengths longer than attainable with jellyfish- or coral-derived FPs using smURFP and IFP2.0; e) allows for functional fusion to hCdt1(30/120) as compared to jellyfish- or coral-derived FPs mAG, eGFP, and mRFP1 which are nonfunctional; and f) allows for deep tissue imaging.
