Synergistic Enhancement (Enh), Suppression (Sup) of tau-induced neurodegeneration, No effect (None), Lethal combination when co-expressed (Lethal).
Overexpression of TOR is known to paradoxically cause a loss-of-function phenotype during development [102]. Overexpression of the Rheb GTPase, however, activates the pathway [99, 100].
Abbreviations: Dominant negative (DN), Loss-of-function allele (LOF), Gain-of-function/constitutively active allele (GOF); UAS (Upstream Activating Sequence) refers to GAL4-responsive transgenes.
Bold face indicate unexpected interactions.
