DOA4

DOS1, MUT4, NPI2, SSV7, UBP4, L000000514, YDR069C
Ubiquitin hydrolase; deubiquitinates intralumenal vesicle (ILVs) cargo proteins; required for recycling ubiquitin from proteasome-bound ubiquitinated intermediates, acts at the late endosome/prevacuolar compartment to recover ubiquitin from ubiquitinated membrane proteins destined for the vacuole; DOA4 has a paralog, UBP5, that arose from the whole genome duplication

DSC3

YOR223W, YOR223W
Subunit of the DSC ubiquitin ligase complex; protein of unknown function that localizes to the ER and vacuole lumen; overexpression affects endocytic protein trafficking; ortholog of fission yeast dsc3

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Identification of Candidate Substrates for the Golgi Tul1 E3 Ligase Using Quantitative diGly Proteomics in Yeast.

Tong Z, Kim MS, Pandey A, Espenshade PJ

Maintenance of protein homeostasis is essential for cellular survival. Central to this regulation are mechanisms of protein quality control in which misfolded proteins are recognized and degraded by the ubiquitin-proteasome system. One well-studied protein quality control pathway requires ER resident, multi-subunit E3 ubiquitin ligases that function in ER-associated degradation (ERAD). Using fission yeast, our lab identified the Golgi Dsc E3 ... [more]
