Mitochondrial translational activator specific for the COX3 mRNA; acts together with Pet54p and Pet494p; located in the mitochondrial inner membrane
Saccharomyces cerevisiae (S288c)
PREY

LEU9

2-isopropylmalate synthase LEU9, YOR108W
Alpha-isopropylmalate synthase II (2-isopropylmalate synthase); catalyzes the first step in the leucine biosynthesis pathway; the minor isozyme, responsible for the residual alpha-IPMS activity detected in a leu4 null mutant; LEU9 has a paralog, LEU4, 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.

Mitochondria are essential organelles whose functions depend on coordinated multiprotein complexes, yet their composition and organization remain incomplete. Here, we present a large-scale map of mitochondrial protein complexes by integrating affinity purification of 740 endogenously GFP-tagged mitochondrial proteins with biochemical co-fractionation of mitochondrial extracts from yeast (Saccharomyces cerevisiae) grown under respiratory conditions. Mass spectrometry identifies 13,716 high-confidence protein associations and ... [more]

Throughput

  • High Throughput

Additional Notes

  • High throughput score cut-off value/description The PPIs are derived from two methods AP-MS and CF-MS. The LLS PPI score is derived from the LLS AP-MS and LLS CF-MS scores. The cutoff for AP-MS is 5.34 and CF-MS is 3.12. If the PPI is detected by both methods and meets the threshold in one of the methods the Average LLS score is taken as the final LLS score for the PPI.
