²For these ORFs, the co-purifying set of proteins were the proteins with high coverage in the mass spectrometric analysis.

³The localization and mass spectrometry data suggest that the asterisked protein forms two complexes, one in the mitochondrion and one in the nucleus (see manuscript text).

⁴The GO annotation was chosen as the significant annotation involving more than 2 of the ORFs.

⁵The POP1 complex was purified using TAP tagged-YLR145W, an uncharacterized essential protein. Although used as the bait, YLR145W was detected in only 1 of 3 mass spectrometric analyses.
