Cullin-2 (CUL2) primarily based cullin-RING ligases (CRL2s) comprise a household of ubiquitin E3 ligases that exist solely in multi-cellular organisms and are essential for mobile processes equivalent to embryogenesis and viral pathogenesis. CUL2 is the scaffold protein that binds one of the interchangeable substrate receptor modules, which consists of adaptor proteins and the substrate receptor protein. The VHL protein is a substrate receptor identified to focus on hypoxia-inducible issue α (HIF1α) for ubiquitination and degradation. Because of its essential function within the ubiquitination of necessary mobile components equivalent to HIF1α, CRL2s have been investigated for his or her organic features and the event of novel therapeutics towards illnesses. Given the significance of CRL2s in organic and biomedical analysis, strategies that effectively produce functional CUL2 proteins will significantly facilitate research on the mechanism and regulation of CRL2s. Here, we report two cost-effective programs for the expression and purification of recombinant human CUL2 from E. coli cells. The purified CUL2

proteins have been ~ 95% pure, may bind their substrate receptor modules, and have been enzymatically read more
