Table 1 Yhr087wp interacting proteins according to the TAP experiments carried out in this work

Atp7p

Subunit d of the stator stalk of mitochondrial F1F0 ATP synthase

Osh7p

Member of an oxysterol-binding protein family with seven members in S. cerevisiae; family members have overlapping, redundant functions in sterol metabolism and collectively perform a function essential for viability

Cmk1p

Calmodulin-dependent protein kinase; may play a role in stress response

Cmk2p

Calmodulin-dependent protein kinase; may play a role in stress response

Sti1p

Hsp90 cochaperone, interacts with the Ssa group of the cytosolic Hsp70 chaperones and activates Ssa1p ATPase activity

Tfg1p

TFIIF (Transcription Factor II) largest subunit; involved in both transcription initiation and elongation of RNA polymerase II;

Cdc33p

Cytoplasmic mRNA cap binding protein and translation initiation factor eIF4E; the eIF4E-cap complex is responsible for mediating cap-dependent mRNA translation via interactions with translation initiation factor eIF4G (Tif4631p or Tif4632p)

Scp160p

Essential RNA-binding G protein effector of mating response pathway, mainly associated with nuclear envelope and ER, interacts in mRNA-dependent manner with translating ribosomes via multiple KH domains, similar to vertebrate vigilins

Tif32p

eIF3a subunit of the core complex of translation initiation factor 3 (eIF3), essential for translation

Tif4631p

Translation initiation factor eIF4G, subunit of the mRNA cap-binding protein complex (eIF4F) that also contains eIF4E (Cdc33p); interacts with Pab1p and with eIF4A (Tif1p); also has a role in biogenesis of the large ribosomal subunit
