Image Processing for Bioluminescence Resonance Energy Transfer Measurement—BRET-Analyzer
A growing number of tools now allow live recordings of various signaling pathways and protein-protein interaction dynamics in time and space by ratiometric measurements, such as Bioluminescence Resonance Energy Transfer (BRET) Imaging. Accurate and reproducible analysis of ratiometric measurements has thus become mandatory to interpret quantitative imaging. In order to fulfill this necessity, w...
متن کاملA bioluminescence resonance energy transfer (BRET) system: application to interacting circadian clock proteins.
We describe a method for assaying protein interactions that offers some attractive advantages over previous assays. This method, called bioluminescence resonance energy transfer (BRET), uses a bioluminescent luciferase that is genetically fused to one candidate protein, and a green fluorescent protein mutant fused to another protein of interest. Interactions between the two fusion proteins can ...
متن کاملAnalysis of in vitro SUMOylation using bioluminescence resonance energy transfer (BRET).
We demonstrated in vitro small ubiquitin-like modifier (SUMO)-mediated modification (SUMOylation) of RanGTPase activating protein-1 (RanGAP1) by using bioluminescence resonance energy transfer (BRET) for studying protein interactions. Renilla luciferase (Rluc) was fused to SUMO, and RanGAP1, the binding partner of SUMO, was fused to enhanced yellow fluorescence protein (EYFP). Upon binding of S...
متن کاملImaging protein interactions with bioluminescence resonance energy transfer (BRET) in plant and mammalian cells and tissues.
FRET is a well established method for cellular and subcellular imaging of protein interactions. However, FRET obligatorily necessitates fluorescence excitation with its concomitant problems of photobleaching, autofluorescence, phototoxicity, and undesirable stimulation of photobiological processes. A sister technique, bioluminescence resonance energy transfer (BRET), avoids these problems becau...
متن کاملIn Vivo Analysis of Protein–Protein Interactions with Bioluminescence Resonance Energy Transfer (BRET): Progress and Prospects
Proteins are the elementary machinery of life, and their functions are carried out mostly by molecular interactions. Among those interactions, protein-protein interactions (PPIs) are the most important as they participate in or mediate all essential biological processes. However, many common methods for PPI investigations are slightly unreliable and suffer from various limitations, especially i...
