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

SLA1

cytoskeletal protein-binding protein SLA1, L000001912, YBL007C
Cytoskeletal protein binding protein; required for assembly of the cortical actin cytoskeleton; interacts with proteins regulating actin dynamics and proteins required for endocytosis; found in the nucleus and cell cortex; has 3 SH3 domains

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.

The deubiquitinating enzyme Doa4p protects cells from DNA topoisomerase I poisons.

DNA topoisomerase I (Top1p) catalyzes changes in DNA topology via the formation of an enzyme-DNA covalent complex that is reversibly stabilized by the antitumor drug, camptothecin (CPT). During S-phase, collisions with replication forks convert these complexes into cytotoxic DNA lesions that trigger cell cycle arrest and cell death. To investigate cellular responses to CPT-induced DNA damage, a yeast genetic screen ... [more]
