DESCRIPTION:
The Von Hippel-Lindau tumor suppressor (VHL) Binding Assay Kit is a homogeneous assay which measures the binding of VHL to the high-affinity VHL fluorescent probe (BDY FL VH032) using Fluorescence Polarization (FP). In addition, the kit includes the VHL inhibitor VH298 for use as an inhibitor control. This assay takes advantage of the fluorescent substrate BDY FL VH032. Using this kit, only one step on a 96-well plate is required. The BDY FL VH032 is incubated with the VHL complex in the presence of a compound of interest to produce a change in fluorescent polarization. The FP signal is measured using a fluorescent microplate reader capable of measuring fluorescence polarization.

- Background: VHL is a tumor suppressor that functions as the substrate recognition subunit of the Cullin2 RING E3 ligase complex (CRL2VHL). CRL2VHL plays important roles in oxygen sensing by targeting hypoxia-inducible factor-alpha (HIF-α) subunits for ubiquitination and degradation. Elongin B (ELOB) and Elongin C (ELOC) are heterodimers that bind to the BC-box motif present in VHL. In this specific E3 ligase complex, the ELOB/ELOC works as an adapter between target proteins and Cullin-2/Rbx1 in VHL-box E3 ubiquitin ligases._x000D_ VHL is targeted by bifunctional molecules such as proteolysis-targeting chimeras to induce degradation of proteins of interest. Design and characterization of VHL binders is an important step in the design of VHL-targeting molecular degraders.
