In a wild-type background, timΔNLS.T:Avic\GFP-YFP behaves as a dominant negative allele, increasing the period length of locomotor activity rhythms by ~1 hour.
tim01; timT:Avic\GFP-YFP flies do not show significant changes in period at different temperatures.
timΔNLS.YFP fails to rescue tim01
Under conditions of constant darkness, tim01; timT:Avic\GFP-YFP flies show abnormal locomotor activity, as in tim01 mutants.
