PET9

AAC2, ANC2, ADP/ATP carrier protein PET9, OP1, L000000004, L000001386, L000004346, YBL030C
Major ADP/ATP carrier of the mitochondrial inner membrane; exchanges cytosolic ADP for mitochondrially synthesized ATP; also imports heme and ATP; phosphorylated; required for viability in many lab strains that carry a sal1 mutation; PET9 has a paralog, AAC3, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)

PHB1

prohibitin subunit PHB1, L000001416, L000001415, YGR132C
Subunit of the prohibitin complex (Phb1p-Phb2p); prohibitin is a 1.2 MDa ring-shaped inner mitochondrial membrane chaperone that stabilizes newly synthesized proteins; determinant of replicative life span; involved in mitochondrial segregation; prohibitin deficiency induces a mitochondrial unfolded protein response (mtUPR)
Saccharomyces cerevisiae (S288c)

Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.

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]

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.

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.
