Tissue specificity：In brain, highest expression is observed in the SCN. Highly expressed in the pyramidal cell layer of the piriform cortex, the periventricular part of the caudate-putamen, many thalamic nuclei, and the granular layer of the cerebellar cortex. Weaker expression is detected in most area of the brain, including cortical and non cortical structures. Expression but no oscillations occurs in the glomerular and mitral cell layers of the olfactory bulb, the internal granular layer of the cerebellum, the cornu ammonis and dentate gyrus of the hyppocampus, the cerebral and piriform cortices. Expressed in the renal cortex (at protein level). Also found in heart, brain, bladder, lumbar spinal cord, spleen, lung, liver, skeletal muscle and testis. {ECO:0000269|PubMed:10521578, ECO:0000269|PubMed:16790549, ECO:0000269|PubMed:24154698, ECO:0000269|PubMed:24603368, ECO:0000269|PubMed:24610784, ECO:0000269|PubMed:9333243, ECO:0000269|PubMed:9427249}.
Induction：In the suprachiasmatic nucleus (SCN), behaves like a day-type oscillator, with maximum expression during the light period. Oscillations are maintained under constant darkness and are responsive to changes of the light/dark cycles. There is a 4 hour time delay between PER1 and PER2 oscillations. The expression rhythms appear to originate from retina. In liver, peak levels at CT9. In the SCN, levels increase by light exposure during subjective night. Circadian oscillations also observed in skeletal muscle, bladder, lumbar spinal cord and liver but not in testis. {ECO:0000269|PubMed:10521578, ECO:0000269|PubMed:11779462, ECO:0000269|PubMed:16790549, ECO:0000269|PubMed:24603368, ECO:0000269|PubMed:9323128, ECO:0000269|PubMed:9333243, ECO:0000269|PubMed:9427249}.
Developmental stage：Expressed in the suprachiasmatic nucleus (SCN) during late fetal and early neonatal life.
