Measuring Kinase Activity at the Single-Cell Level with Kinase Translocation Reporters (KTRs)

Posted by Beth Kenkel on Jul 26, 2018 8:46:55 AM

Kinases: they regulate many proteins, with ~1/3 of human proteins predicted to be phosphorylated on at least one site. Phosphorylation is particularly important for regulating signal transduction and measuring kinase activity at the single-cell level can aid in drawing connections between signaling activity and cell phenotype. One method for monitoring live single-cell kinase activity is FRET, but FRET reporters are challenging to design and difficult to multiplex. The Covert Lab provides an alternative tool with their Kinase Translocation Reporters (KTRs) whose cellular localization serves as a proxy measurement of kinase activity. The key advantage of KTRs is that they are easy to create and simple to multiplex.

Technologies Enabled by NanoLuc® Luciferase

Researchers have been sharing plasmids ever since there were plasmids to share. Back when I was in the lab, if you read a paper and saw an interesting construct you wished to use, you could either make it yourself or you could “clone by phone”. One of my professors was excellent at phone cloning with labs around the world and had specific strategies and tactics for getting the plasmids he wanted. Addgene makes it so much easier to share your constructs from lab to lab. Promega supports the Addgene mission statement: Accelerate research and discovery by improving access to useful research materials and information. Many of our technology platforms like HaloTag® Fusion Protein, codon-optimized Firefly luciferase genes (e.g., luc2), and NanoLuc® Luciferase are available from the repository. We encourage people to go to Addgene to get new innovative tools. Afterall, isn’t science better when we share?
