The DUG gene of Drosophila melanogaster encodes a structural and functional homolog of the S. cerevisiae SUG1 predicted ATPase associated with the 26S proteasome
The DUG gene of Drosophila encodes a putative ATPase that is a structural and functional homolog of the yeast SUG1 product. When introduced into S. cerevisiae, the Drosophila DUG gene rescued the lethality associated with a SUG1 mutant. Anti-DUG antibodies recognized a protein that migrated in high molecular weight complexes, along with components of the 26S proteasome, and also immunoprecipitated components of the 26S proteasome from embryonic extracts. Proteins recognized by the affinity-purified antibody raised against DUG were localized in either a punctate cytoplasmic distribution or in the nucleus, depending on the cell type, consistent with the subcellular localization of the 26S proteasome in various cell types.
