Abstract excerpt

The ubiquitin-activating enzyme E1 catalyzes the first step in the ubiquitin conjugation pathway. Previously, we have cloned and sequenced the cDNA for human E1. Expression of the E1 cDNA in the ts20 cell line, which harbors a thermolabile E1, abrogated the phenotypic defects associated with this line. However, little is known of the cell biology of the E1 protein or the nature of the E1 doublet. Thus, we...
