The enhanced brightness and small size of NanoLuc® luciferase make it an ideal protein fusion tag that provides a sensitive and quantitative method for monitoring changes in intracellular protein abundance.
The intracellular level of many proteins is tightly controlled by a balanced rate of synthesis and degradation, and many proteins are maintained at low intracellular abundance by targeting for proteolysis via the ubiquitin/proteasome system. Certain conditions, such as cellular stress, result in increased protein stabilization causing accumulation and subsequent activation of downstream signaling events. Regulation of protein stability is the primary method of regulation for many signaling pathways. The ability to monitor changes in the intracellular protein abundance is valuable for understanding the cellular response to specific treatment or conditions.
Measuring Intracellular Protein Lifetime Dynamics Using NanoLuc® Luciferase
In partnership with Horizon Discovery, a number of reporter cell lines have been created using adenovirus-mediated genome editing to insert NanoLuc® luciferase and create a gene encoding a fusion protein at the endogenous locus of the protein of interest.
