Promega & SEBBM Live Webinar: “Studying Endogeneous Protein Dynamics through CRISPR-Mediated Tagging with a Luminescent Peptide” (16/09/20)
Promega and the SEBBM organize this live webinar. Date: Wednesday, September 16, 2020 Time: 05:30 PM Central European Summer Time Duration: 1 hour
CRISPR/Cas9 technology has revolutionized genome editing by offering a simple method to tag proteins at endogenous loci, facilitating the study of protein biology while maintaining proper transcriptional regulation, expression levels and stoichiometry with binding partners. By contrast, ectopic expression of tagged proteins can lead to a variety of overexpression artifacts, like mislocalization, aggregation, or dysregulation of degradation. HiBiT, an 11-amino-acid bioluminescent peptide, represents an ideal tag for endogenous labeling due to its small size and large, linear dynamic range. In this live talk, we will highlight an efficient, cloning-free method for knock-in of HiBiT. We will demonstrate that this represents a scalable strategy for studying protein dynamics, including abundance, localization, modification, and interactions. We will also focus on the application of this method to monitoring PROTAC-induced protein degradation, highlighting the importance of endogenous expression in achieving biologically meaningful results.
