Homozygous, yarΔ1A-2/yarΔHR2 and yarΔHR2/Df(1)y-ac females show a significant decrease in the level of total nighttime sleep. The average length of each nighttime sleep bout is reduced compared to controls, and coincides with an increase in the number of sleep episodes.
Homozygous and yarΔHR2/Df(1)y-ac females do not increase total daytime sleep or the duration of daytime sleep bouts following sleep deprivation (in contrast to control flies). yarΔ1A-2/yarΔHR2 females do increase total daytime sleep and the duration of daytime sleep bouts following sleep deprivation.
lncRNA:yarΔHR2 is rescued by lncRNA:yar+t6
