Part:BBa_M50439

coding sequence bioluminescent "pHlash"reporter for intracellular pH

This is a genetically encodable probe that will report cytosolic pH in vivo of mammalian, yeast, or bacterial cells, through Bioluminescence Resonance Energy Transfer (BRET) data. The device utilizes a Rluc8 luciferase-cpVenus fluorophore fusion, where the Rluc8 luciferase protein exhibits pH-dependent activity. The luciferase cleaves a luciferin substrate, specifically coelenterazine, emitting a photon to excite the fluorophore, causing emission of light. Since luciferase activity rate depends on the pH of the environment, the emission by the fluorophore is an indicator of pH, which can be calibrated or relatively measured by calculating the BRET ratio (475nm:525nm recommended).

This part is just the coding sequence for the fusion of the proteins, which are linked by the tri-amino acid sequence Ala-Glu-Leu.
