Recombinant human von Hippel-Lindau (VHL) protein is a tumor suppressor encoded by the *VHL* gene, mutations of which are linked to von Hippel-Lindau disease, renal cell carcinoma, and other cancers. The VHL protein, part of the E3 ubiquitin ligase complex, plays a critical role in oxygen-sensing pathways by targeting hypoxia-inducible factors (HIFs) for proteasomal degradation under normoxic conditions. Structurally, it contains a β-domain for substrate binding (e.g., HIF-1α) and an α-domain facilitating interactions with elongin B/C. Recombinant VHL is typically produced in bacterial or mammalian expression systems, often tagged with His or GST for purification. Its applications span cancer research, drug discovery (e.g., HIF pathway inhibitors), and structural studies to decipher mechanisms of substrate recognition and disease-associated mutations. Engineered variants (e.g., VHL30) are also used in targeted protein degradation technologies like PROTACs. Studying recombinant VHL aids in understanding hypoxia response dysregulation in tumors and developing therapeutic strategies.
