Biological Activity for BromoTag® AGB1
BromoTag® AGB1 is a highly selective and potent "Bump & Hole" TAG Degrader (DC50,6h < 15 nM, t1/2 for protein degradation = 40 min). BromoTag AGB1 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 AGB1 drives formation of a ternary complex between VHL and the "BromoTagged" protein, leading to ubiquitination of the protein and its subsequent proteasomal degradation. BromoTag AGB1 is highly selective for Brd4BD2 L387A over wild-type, and is broadly selective across the proteome. BromoTag AGB1 exhibits no cytoxicity in several cancer relevant cell lines. BromoTag AGB1 is suitable for in vivo studies.
Negative control BromoTag® cis-AGB1 (Cat. No. 7687) also available.
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.
A polyclonal antibody targeting Brd4BD2 L387A (Cat. No. NBP3-17999) is available from Bio-Techne sister brand Novus Biologicals.

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.
