Purity: > 90% by SDS - PAGE Format: Liquid. In 20mM Tris-HCl buffer (pH 8.0) containing 2mM DTT, 10% glycerol, 200mM NaCl. NAE1 (NEDD8-activating enzyme E1 regulatory subunit) belongs to the ubiquitin-activating E1 family. This protein binds to the beta-amyloid precursor protein. Beta-amyloid precursor protein is a cell surface protein with signal-transducing properties, and it is thought to play a role in the pathogenesis of Alzheimer's disease. NAE1 participates in a novel ubiquitinylation-related pathway involving the ubiquitin-like molecule NEDD8. Also, this protein is required for cell cycle progression through the S/M checkpoint. Recombinant human NAE1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.
