E3 ubiquitin ligase of NEDD4 family; regulates many cellular processes including MVB sorting, heat shock response, transcription, endocytosis, ribosome stability; mutant tolerates aneuploidy; autoubiquitinates; ubiquitinates Sec23p and Sna3p; deubiquitinated by Ubp2p; activity regulated by SUMO ligase Siz1p, in turn regulates Siz1p SUMO ligase activity; required for efficient Golgi-to-ER trafficking in COPI mutants; human homolog implicated in Liddle syndrome

MFP1, TRG1, protein disulfide isomerase PDI1, L000001360, YCL043C
Protein disulfide isomerase; multifunctional protein of ER lumen, essential for formation of disulfide bonds in secretory and cell-surface proteins, unscrambles non-native disulfide bonds; key regulator of Ero1p; forms complex with Mnl1p that has exomannosidase activity, processing unfolded protein-bound Man8GlcNAc2 oligosaccharides to Man7GlcNAc2, promoting degradation in unfolded protein response; PDI1 has a paralog, EUG1, that arose from the whole genome duplication

Protein-peptide

An interaction is detected between a protein and a peptide derived from an interaction partner. This includes phage display experiments.

Comparative analysis of Saccharomyces cerevisiae WW domains and their interacting proteins.

Hesselberth JR, Miller JP, Golob A, Stajich JE, Michaud GA, Fields S

BACKGROUND: The WW domain is found in a large number of eukaryotic proteins implicated in a variety of cellular processes. WW domains bind proline-rich protein and peptide ligands, but the protein interaction partners of many WW domain-containing proteins in Saccharomyces cerevisiae are largely unknown. RESULTS: We used protein microarray technology to generate a protein interaction map for 12 of the ... [more]

Throughput

  • High Throughput

Additional Notes

  • A protein microarray was probed with the third WW domain from RSP5 (YER125W_WW3).
  • High Throughput: Each WW-domain was used as a probe for two separate protein microarrays. Only those in which four independent interactions were osbserved were considered high-confidence (i.e. significant signals found for proteins printed in duplicate on two separate microarrays).

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

Negative Genetic

Mutations/deletions in separate genes, each of which alone causes a minimal phenotype, but when combined in the same cell results in a more severe fitness defect or lethality under a given condition. This term is reserved for high or low throughput studies with scores.
