RPN11

MPR1, proteasome regulatory particle lid subunit RPN11, L000002976, L000002965, YFR004W
Metalloprotease subunit of 19S regulatory particle; part of 26S proteasome lid; couples the deubiquitination and degradation of proteasome substrates; involved, independent of catalytic activity, in fission of mitochondria and peroxisomes; protein abundance increases in response to DNA replication stress

ELP1, KTI7, TOT1, Elongator subunit IKI3, L000003563, YLR384C
Subunit of Elongator complex; Elongator is required for modification of wobble nucleosides in tRNA; maintains structural integrity of Elongator; homolog of human IKAP, mutations in which cause familial dysautonomia (FD)

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 cell cycle specific protein interaction networks of the yeast 26S proteasome complex by the QTAX strategy.

Kaake RM, Milenkovic T, Przulj N, Kaiser P, Huang L

Ubiquitin-proteasome dependent protein degradation plays a fundamental role in the regulation of the eukaryotic cell cycle. Cell cycle transitions between different phases are tightly regulated to prevent uncontrolled cell proliferation, which is characteristic of cancer cells. To understand cell cycle phase specific regulation of the 26S proteasome and reveal the molecular mechanisms underlying the ubiquitin-proteasome degradation pathway during cell cycle ... [more]

Throughput

  • High Throughput

Additional Notes

  • Proteasome interacting proteins (PIPs) were identified using QTAX (quantitative analysis of tandem affinity purified in vivo cross-linked (X) protein complexes). TAP-tagged Rpn11 and in vivo formaldehyde cross-linking were used in the experiment.
