UbcD4, a ubiquitin-conjugating enzyme in Drosophila melanogaster expressed in pole cells

The ability to destroy a particular protein at a particular time is central to the regulation of many cellular processes. Selective proteolysis in eukaryotic cells is carried out primarily by the ubiquitin-proteasome pathway. Attachment of a ubiquitin polymer to an unwanted protein causes it to be degraded by the proteasome. Several classes of enzyme, known… (More)
