Abstract / Description of output
In fission yeast, the only known essential function of Ned8p is the modification of the cullin, Pcu1p, and subsequent Cullin-RING-Ligase (CRL) activation and substrate ubiquitination. We show here that a functional Pcu1p mutant, deleted for its C-terminal autoinhibitory domain, which negates the requirement of neddylation for ligase activity, is unable to rescue the loss of neddylation. These findings suggest that the neddylation of non-cullin substrate(s) are required for Schizosaccharomyces pombe viability.
