^aA dash indicates that the gene was not identified as a regulator of Ty in the screen. Activators are genes that, when mutated, decrease Ty mobility, and repressors are genes that, when mutated, increase Ty mobility.

^bThe number of Ty regulatory genes identified in the screen that were also identified in one or more additional screens divided by the total number of Ty1 regulatory genes identified in the screen.
