Peptide or Protein

NEDD8 Protein

A ubiquitin-like protein that functions in CELL CYCLE regulation and embryogenesis. It is attached covalently to its substrates following activation by the UBIQUITIN-ACTIVATING ENZYME E1-UBA3 enzyme complex. NEDD8 attaches to CULLINS, activating their E3 UBIQUITIN LIGASE activity, to promote polyubiquitination and degradation of CYCLINS and regulatory proteins
