Biological Activity for BromoTag® AGB3

BromoTag® ABG3 is a selective "Bump & Hole" TAG Degrader (DC50 210 - 290 nM, protein degradation t½ = 113 min, Dmax = 92%). BromoTag AGB3 comprises a VHL E3 ligase ligand joined by a linker to a (+)-JQ1 (Cat. No. 4499) derivative (the "bump" bearer) that selectively binds the Brd4BD2 L387A variant (the "hole"). In cell lines expressing a fusion of the target protein with the tag, Brd4BD2 L387A, BromoTag AGB3 drives formation of a ternary complex between VHL and the "BromoTagged" protein, leading to ubiquitination of the protein and its subsequent proteasomal degradation.

BromoTag® is a registered trademark of the University of Dundee and is used under license.

Brd4BD2 L387A can be expressed as a fusion with a target protein of interest using genome engineering techniques via CRISPR-mediated locus-specific knock-in. See protocol for more information.

Targeted Protein Degradation Poster

Targeted Protein Degradation Poster

Degraders (e.g. PROTACs) are bifunctional small molecules, that harness the Ubiquitin Proteasome System (UPS) to selectively degrade target proteins within cells. They consist of three covalently linked components: an E3 ubiquitin ligase ligand, a linker and a ligand for the target protein of interest. Authored in-house, this poster outlines the generation of a toolbox of building blocks for the development of Degraders. The characteristics and selection of each of these components are discussed. Presented at EFMC 2018, Ljubljana, Slovenia

Validating Targets for TPD Using dTAG Poster

Validating Targets for TPD Using dTAG Poster

The dTAG platform offers a generalizable strategy to degrade, in principle, any intracellular protein of interest (POI) and is a useful strategy for exploration and validation of targets. This poster presents a workflow solution for target validation, from custom TAG knock-in cell-lines for your POI, different dTAG Degraders to knockdown you POI, to automated assays for protein degradation using Simple WesternTM instruments. Data are also presented on the use of an antibody that recognizes the TAG domain (FKBP12F36V) for detection of degradation. Presented at TPD Europe, March 2022, London, UK.
