BAIT
AHA1
YDR214W
Co-chaperone that binds Hsp82p and activates its ATPase activity; plays a role in determining prion variants; similar to Hch1p; expression is regulated by stresses such as heat shock; protein abundance increases in response to DNA replication stress

SLI2, serine/threonine protein kinase YPK1, L000002541, YKL126W
Serine/threonine protein kinase; phosphorylates and downregulates flippase activator Fpk1p; inactivates Orm1p and Orm2p (inhibitors of serine:palmitoyl-coenzyme A transferase) by phosphorylation in response to compromised sphingolipid synthesis; mutations affect receptor-mediated endocytosis and sphingolipid-mediated and cell integrity signaling pathways; homolog of mammalian kinase SGK; YPK1 has a paralog, YPK2, that arose from the whole genome duplication

Affinity Capture-MS
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.
Publication
The social and structural architecture of the yeast protein interactome.
Cellular functions are mediated by protein-protein interactions, and mapping the interactome provides fundamental insights into biological systems. Affinity purification coupled to mass spectrometry is an ideal tool for such mapping, but it has been difficult to identify low copy number complexes, membrane complexes and complexes that are disrupted by protein tagging. As a result, our current knowledge of the interactome ... [more]

Quantitative Score
- 2.0 [Score_FDR+correlation]
Throughput
- High Throughput
Additional Notes
- Protein interactions were identified using statistically significant enrichment of the proteins in the forward and reverse pull-downs, as well as making use of the profile similarities of interacting proteins in a correlation analysis. High confidence interactions have a total score >=2. This score is a sum of the FDR score of the forward pull-down + FDR score of the reverse pull-down + correlation score.
