Expression and purification of functional recombinant CUL2•RBX1 from E. coli.

ABSTRACT: Cullin-2 (CUL2) based cullin-RING ligases (CRL2s) comprise a family of ubiquitin E3 ligases that exist only in multi-cellular organisms and are crucial for cellular processes such as 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 known to target hypoxia-inducible factor α (HIF1α) for ubiquitination and degradation. Because of its critical role in the ubiquitination of important cellular factors such as HIF1α, CRL2s have been investigated for their biological functions and the development of novel therapeutics against diseases. Given the importance of CRL2s in biological and biomedical research, m
