Transcripts cycle with almost identical phase, amplitude and peak levels as do the endogenous per transcript. Genomic constructs containing the same upstream regions as this construct and the per coding region can restore virtually normal circadian rhythms to per01 mutants (Citri, Nature 326: 42--47; Hamblen, J. Neurogenet. 3: 249--291).
