Kinetics of rat CSD-C2 binding to H3.3 RNA

Cold-shock domain containing protein C2 (CSD-C2; also known as PIPPin) is an RNA-binding protein conserved in the evolution that interacts with the 3’-untranslated region (3’-UTR) of rat H1.0 and H3.3 histone messengers. Biolayer interferometry (BLI) is a technique that measures changes in an interference pattern generated from visible light, reflected from an optical layer, and a biolayer which contains molecules of interest. In this study, we used the BLI methodology in order to analyze and describe the binding properties of CSD-C2 and the mRNA encoding the rat brain histone protein H3.3. Recombinant CSD-C2 was incubated with in vitro transcribed, and biotinylated H3.3 RNA fragments bound…
