Luciferase assay is used to find if a protein can repress or activate the expression of a target gene. Luciferase assay is produced in laboratory with the help of genetic engineering technique. The gene is inserted into organisms such as silkworms, mice and potatoes for production of proteins. Luciferase assay is used for assessing the transcriptional activity in the cells and to find the ATP in cells for kinase activity. Luciferase assay acts as an ATP sensor protein by biotinylation which immobilizes luciferase on surface of cell by binding to a complex. Environmental factors can cause discrepancies between bioluminescence intensity and tumor burden to change the proliferative activity. It is defined as a heat-sensitive protein which is used in studying denaturation of proteins and testing protective capacities of proteins.
