Tissue specificity：In the brain, high expression in SCN during the subjective day. Constitutive expression in the cornu ammonis and in the dentate gyrus of the hyppocampus. Also expressed in the piriform cortex and the glomeruli of the olfactory bulb, and at a lower extent in the cerebral cortex. Not expressed in the pars tuberalis and the Purkinje neurons. Also expressed in adipose tissue (white and brown), heart, kidney, bladder, lumbar spinal cord, skeletal muscle, spleen, lung, pancreas and liver with highest levels in skeletal muscle and liver and lowest levels in spleen. {ECO:0000269|PubMed:15860628, ECO:0000269|PubMed:21035761, ECO:0000269|PubMed:23531614, ECO:0000269|PubMed:24154698, ECO:0000269|PubMed:24603368, ECO:0000269|PubMed:9427249, ECO:0000269|PubMed:9428527}.
Induction：Oscillates diurnally in several tissues, mainly in central nervous system and liver (at protein levels) but also in pancreas, bladder and lumbar spinal cord. 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:15860628, ECO:0000269|PubMed:18419266, ECO:0000269|PubMed:19917250, ECO:0000269|PubMed:23531614, ECO:0000269|PubMed:24603368, ECO:0000269|PubMed:9427249, ECO:0000269|PubMed:9428527}.
Developmental stage：Expressed in the SCN during late fetal and early neonatal life. Expression increases during adipogenesis. {ECO:0000269|PubMed:21035761, ECO:0000269|PubMed:9427249}.
