Cloning of novel luciferase gene from deep3sea planktonic worm Tomopteris helgolandica as a way to improve visualization of in vivo protein dynamics The study of in vivo protein dynamics is growing rapidly due to technological advancement. However, current methodologies have many limitations and there is a strong need for improvements. Bioluminescence microscopy is a promising technology in that it does not need excitation by light and seeing photon emissions are a result of a chemical reaction, results are very speciAic and quantiAiable. However, a major setback in bioluminescence microscopy is the strength of the signal emitted. Whilst genetically enhanced luciferases have improved the status quo, variability of their half3live, and variability in their enzyme activity remain obstacles 1 . Fundamentally, there is a need for new luciferases that can overcome the limitations presented by existing luciferases. The successful cloning of a novel luciferase gene will ultimately improve on current methodologies available for visualizing in vivo protein dynamics. Not only will this add to the colour palette of available luciferases, it will also introduce a novel emission spectrum that may enhance multi3probe analysis in bioluminescent microscopy. Ultimately, it may be used as a tool to enable scientists to identify any pathological deviations associated with in vivo protein dynamics, resulting in the potential development of applicable therapeutic agents. We aim to identify and clone the luciferase gene from Tomopteris helgolandica, determine its physical3chemical parameters through qualitative and quantitative analysis and compare the emission signal with other commercially available luciferases. We hypothesize that if the luciferase responsible for generating bioluminescence in the organism T. helgolandica is cloned, it will improve on current methodologies available for visualizing in vivo protein dynamics. 3 SufAicient funding from a corporate or government body 3 Zooplankton sample from eastern tropical PaciAic Ocean water columns.
