BAIT

RPT5

YTA1, proteasome regulatory particle base subunit RPT5, L000002555, YOR117W
ATPase of the 19S regulatory particle of the 26S proteasome; one of six ATPases of the regulatory particle; involved in the degradation of ubiquitinated substrates; recruited to the GAL1-10 promoter region upon induction of transcription; similar to human TBP1
Saccharomyces cerevisiae (S288c)

UBI4

SCD2, UB14, ubiquitin, L000002414, YLL039C
Ubiquitin; becomes conjugated to proteins, marking them for selective degradation via the ubiquitin-26S proteasome system; essential for the cellular stress response; encoded as a polyubiquitin precursor comprised of 5 head-to-tail repeats; protein abundance increases in response to DNA replication stress

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.

Characterization of the proteasome interaction network using a QTAX-based tag-team strategy and protein interaction network analysis.

Guerrero C, Milenkovic T, Przulj N, Kaiser P, Huang L

Quantitative analysis of tandem-affinity purified cross-linked (x) protein complexes (QTAX) is a powerful technique for the identification of protein interactions, including weak and/or transient components. Here, we apply a QTAX-based tag-team mass spectrometry strategy coupled with protein network analysis to acquire a comprehensive and detailed assessment of the protein interaction network of the yeast 26S proteasome. We have determined that ... [more]

Throughput

  • High Throughput

Additional Notes

  • #LPPI
  • Interaction was found with RPL40A, but it is relevant for ubiquitin so UBI4 was indicated here as the interactor rather than RPL40A
  • Likely protein-protein interaction

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.
