Synthetic lethality(0 or 1,YPD)	Synthetic lethality (0 or 1), obtained from the YPD.
Co-induced by(YPD)	Factor that induces expression of both genes, obtained from the YPD.
Co-repressed by(YPD)	Factor that suppresses expression of both genes, obtained from the YPD.
Not affected by(YPD)	Factor that does not affect expression of these genes, obtained from the YPD.
Interologs	The number of interactions that exist between the interacting protein and the ortholog of other species, obtained from the Database of Interacting Proteins(*4).
Expression similarity (BRITE)	Expression data obtained from KEGG BRITE(*5). (High values only, 0.9 or greater)
Alternative path with 1 intervening protein	The number of paths other than this interaction mediated by one intermediate protein, calculated from the full data.
