WebThe essential functions of NEDD8 are mediated via distinct surface regions, and not by polyneddylation in Schizosaccharomyces pombe. Girdwood D, Xirodimas DP, Gordon C. PLoS One. 6(5):e20089. Pubmed; In the family with ubiquitin. Alexandru G, Pariente N, Xirodimas D. EMBO Rep. 12(9):880-2. Pubmed; Stable-isotope labeling with amino acids … Neddylation (also NEDDylation) is the process by which the ubiquitin-like protein NEDD8 is conjugated to its target proteins. This process is analogous to ubiquitination, although it relies on its own E1 and E2 enzymes. No NEDD8-specific E3 has yet been identified and it is possible that the Neddylation … See more NEDD8 (neural-precursor-cell-expressed developmentally down-regulated 8) is a protein involved in the regulation of cell growth, viability and development. See more Neddylation is involved in the pathogenesis of Alzheimer's disease where its activation appears to drive neurons into apoptosis by initiating cell cycle reentry. Also, evidence … See more NEDD8 links itself to a protein through an isopeptide linkage between its carboxy-terminal glycine and the lysine of the substrate. The neddylation of the substrate causes in … See more doi:10.1371/journal.pone.0043391 See more

Webvirus-associated ubiquitin-specific protease; Polyneddylation; Polyubiquitination; Ubiquitin-specific protease 7 1. Introduction Protein degradation in eukaryotic cells is mediated by either lysosome or proteasome pathway. Lysosome-mediated degra-dation pathway is involved in degradation of 10–20% proteins WebJun 12, 2015 · An in vitro mechanistic study on the formation of polyneddylation chains on cullin-1 suggested that the formation of chain linkages may be a general phenomenon for ubiquitin-like modifiers [20]. Here, we examine whether lysine residues on NEDD8 play distinct roles in protein neddylation and the subsequent activation of CRL E3 ligases. WebImmunocytochemistry assay confirmed that USP7 co‑localizes with PP2A in the cytoplasm and nucleus of HeLa cells. Moreover, western blotting and immunoprecipitation were performed to determine whether polyubiquitination and polyneddylation of PP2A were formed. The results of the present study demonstrated that USP7 was a deubiquitinating ... onslow brick
