摘要:
Neural precursor cell expressed, developmentally clown-regulated gene 8 (NEDD8) is a recently discovered ubiquitin-like posttranslational modifier. NEDD8 acts predominantly as a regulator of ubiquitin-protein ligases and as a decoy for proteins targeted for proteasomal degradation. It thereby controls key events in cell cycle Progression and embryogenesis. Deneddylase-1 (DEN1/NEDP1/SENP8) features a selective peptidase activity converting the proNEDD8 precursor to its mature form and an isopeptidase activity deconjugating NEDD8 from substrates Such as cullins and p53. In this study, we describe a high-throughput screening (HTS)-compatible time-resolved fluorescent resonance energy transfer (TR-FRET) assay measuring the peptidase activity of DEN1.
