4. Compared to the wild type, both per mutants showed reduced longevity and decreased startle-induced locomotion in aging flies, while spontaneous locomotor activity was not impaired.

21. Natural variations in the per gene can modulate the splicing efficiency of the dmpi8 intron and the daily distribution of activity. PMID: 23152918

23. Data indicate that the period (PER) loss-of-function mutant flies were arrhythmic in laboratory condition but displayed weak rhythmic emergence under seminatural condition. PMID: 22855572
24. In prothoracic gland cells associated with the CNS, however, per transcription is markedly amplified following 12-h light exposure, resulting in the manifestation of day-night rhythms in nuclear PER immunostaining levels and spontaneous Ca2+ spiking. PMID: 22713751
25. This study demonistrated that combined a null mutation in the clock gene period (per(01)) that abolishes circadian rhythms, with a hypomorphic mutation in the (sni(1)), which displays oxidative stress induced neurodegeneration. PMID: 22227001
26. A key temporal delay in the circadian cycle of Drosophila is mediated by a nuclear localization signal in the timeless protein. PMID: 21515571
27. kinetics of PER degradation with DBT(S) in cell culture resembles that with wild-type DBT and posits that, in flies DBT(S) likely does not modulate the clock by simply affecting PER degradation kinetics PMID: 21659538
28. CTRIP destabilizes CLK protein in a PER-independent manner and helps degradation of phosphorylated PER and TIM in the morning PMID: 21525955
