Recombinant Human NEDD8

Background: NEDD8 (neural precursor cell expressed, developmentally down-regulated 8) is a small ubiquitin-like modifier that conjugates to target proteins in a process called NEDDylation. The best-characterized substrates are cullin family proteins, where NEDD8 attachment activates cullin-RING E3 ubiquitin ligases (CRLs), promoting ubiquitin transfer to specific substrates and regulating protein turnover. NEDDylation is reversible: NEDD8 is removed by deneddylases such as the COP9 signalosome and NEDP1, allowing dynamic control. NEDD8 pathway influences cell cycle progression, DNA repair, signal transduction, and development. Dysregulation of NEDDylation is implicated in cancer and neurodegeneration, making the pathway a therapeutic target.
