Tissue specificity：Widely expressed. Found in heart, brain, placenta, lung, liver, skeleatal muscle, kidney and pancreas. High levels in skeletal muscle and pancreas. Low levels in lung. Isoform 2 is expressed in keratinocytes (at protein level). {ECO:0000269|PubMed:9427249}.
Induction：Oscillates diurnally. Rhythmic levels are critical for the generation of circadian rhythms in central as well as peripheral clocks. Targeted degradation of PER and CRY proteins enables the reactivation of CLOCK-ARTNL/BMAL1, thus initiating a new circadian transcriptional cycle with an intrinsic period of 24 hours. {ECO:0000269|PubMed:14750904}.
