[Abstract]  Nedd8 is a small ubiquitin-like protein (9 kDa) covalently attached to a conserved lysine residue of a cullin protein which is part of cullin-RING ligases (CRLs). CRLs are major E3 ligases important for protein ubiquitination in the ubiquitin-proteasome pathway (UPP). The activity of CRLs is regulated by cycles of neddylation (CulA-N8, ~98 kDa) and deneddylation (CulA ~89 kDa). The COP9 signalosome (CSN) and Deneddylase A (DenA) are capable of cleaving the isopeptide bond between Nedd8 and ...

[Abstract]  Leishmania is a genus of trypanosomatid protozoa and is the parasite responsible for the disease leishmaniasis. These protozoa, regulate their gene expression in an atypical way, compared to other higher eukaryotes. The regulation of gene expression is characterized by a predominance of post-transcriptional over pre-transcriptional regulatory mechanisms (Clayton, 2002). Thus proteomic analysis has proven an essential tool for understanding pathways implicated in Leishmania ...
