Investigate Ternary Complex Formation

Targeted degradation via small molecule degraders such as PROTACs or molecular glues require forming a ternary complex that consists of target protein:degrader compound:E3 ligase component. Ternary complex formation is the first mechanistic step required for target ubiquitination and degradation via the ubiquitin proteasome pathway, representing a key step in optimizing effective degrader compounds. The NanoBRET® Ternary Complex Starter Kits provide the tools to create target-specific assays for live-cell detection of complex formation with either the VHL (von Hippel-Lindau disease tumor suppressor) or CRBN (cereblon) E3 ligase components. These assays use NanoBRET® technology, a proximity-based method dependent upon energy transfer from a luminescent donor target protein to a fluorescent acceptor and can be performed using either endpoint or kinetic format to monitor the rate and stability of complex formation. The ratio of the bioluminescent and fluorescent signal in the NanoBRET® assay means you can measure ternary complex formation during target protein degradation and simultaneously monitor target protein levels.

Ternary Complex Assay Overview

PROTAC Ternary Complex Formation Assay Overview

How to Get Started

  1. Create the bioluminescent donor protein, which is the target for degradation. The donor protein can be created as a NanoLuc® fusion protein with the provided NanoLuc® cloning vectors or as an endogenous target tagged with HiBiT by CRISPR-Cas9 gene editing. Express the NanoLuc® fusion either transiently or stably in any cell line that can be transfected. Transfect the LgBiT expression vector into HiBiT CRISPR cell lines to produce binary complementation in the cell. The NanoLuc®-BRD4 FL Fusion Vector is provided as a positive control.
  2. Introduce the HaloTag®-VHL or CRBN fusion protein via transient transfection by either co-transfecting with the NanoLuc® fusion protein or the LgBiT vector if using a HiBiT CRISPR cell line. Labeled HaloTag® fusion protein will serve as the fluorescent acceptor in the BRET assay. HaloTag® protein, expressed from the HaloTag® Control Vector, is used as a negative control.
  3. Treat cells with degrader compounds to induce ternary complex formation. If monitoring kinetic ternary complex stability, protein level or both is desired, perform experiments with and without MG132.
  4. Add the NanoBRET® Nano-Glo® reagents, endpoint or kinetic, which provide the substrate for the donor protein and the fluorescent NanoBRET® HaloTag® 618 Ligand for the acceptor protein. Measure the donor and acceptor signal using filtered luminescence, and determine NanoBRET® ratio. Ternary complex formation results in energy transfer between the donor and acceptor, increasing the NanoBRET® signal.

Monitor Ternary Complex Formation and Target Protein Levels in the Same Assay

NanoBRET® Ternary Complex Formation Assays are well suited for live-cell monitoring of the ternary complex that forms between the target protein and E3 ligase component when treated with targeted degradation compounds, such as PROTACs and molecular glues. The assay can provide mechanistic understanding of differences in degrader compound efficacy, perform compound optimization studies or confirm mechanism of action for on- and off-target degradation. Here we show NanoBRET® ternary complex formation for both a PROTAC (NanoLuc®-BRD4:HaloTag®-VHL fusion proteins) and also a molecular glue (NanoLuc®-CK1α:HaloTag®-CRBN fusion proteins) using transiently transfected vectors in HEK293 cells. Since the target being degraded in both assays is the donor protein, its protein level is monitored separately in the same assay. Treatment with the proteasome inhibitor MG132 can be included to increase assay window but omitted when determining the effect on target protein levels.

Measuring ternary complex formation and protein levels

Measure the Kinetics of Ternary Complex Formation

The NanoBRET® Nano-Glo® Kinetic Detection System provides extended live-cell measurement of ternary complex formation to determine how changes in degradation compound composition will affect the kinetics of ternary complex formation, stability or both in live cells. Here we show ternary complex formation using an endogenously tagged protein, HiBiT-BRD4, with expression of LgBiT and HaloTag®-VHL or HaloTag®-CRBN fusion proteins in HEK293 cells in the presence of MG132. Varying kinetic increases of ternary complex formation are observed with each PROTAC for the same target.
