Several endogenous factors have been linked to rhythmicity or circadian behavior of living organisms. In Drosophila, the genes period (dPer) and timeless (tim), and in Neurospora frequency (frq), have been proposed to be responsible for their circadian rhythm. Recently human and mouse genes encoding a basichelix-loop-helix (bHLH) and Per-ARNT-Sim (PAS)-domain with significant similarity to the Drosophila Period have been reported. The cDNA sequences of hPER and mPer1 (also named RIGUI) are predicted to encode for proteins of length 1290 and 1291 amino acids respectively. Homologues of mPer1 designated Per 2 (1257 aa) and Per3 (1113 aa) have also been cloned. Both Per1 and Per2 levels show circadian rhythm in the SCN and eyes. It has been suggested that mPer regulates neuronal activity in the SCN. Using genetic approach, a single mutation (A to T in the Clock gene affects circadian rhythmicity in mice. Clock has been mapped to chromosome 5. Mouse Clock encodes a transcription factor, a single polypeptide chain of 855 aa (predicted calculated mol wt ~97kD; pI 6.52; hClock, 846 aa). Clock is abundantly expressed in brain (SCN, pyrifom cortex, hippocampus) as well as in other tissues (eye, total brain, tested, ovaries, liver, heart, lung, and kidney). Although, Clock is constitutively expressed (not rhythmic) in the SCN, it may still be an important component of circadian machinery.
