Circadian rhythm is one of the most fascinating and complex biological phenomenon's. The circadian clock controls biological activities on daily light-dark cycles in species from cyanobacteria to humans. The circadian clock has three major components: A photoactive pigment (chromophore) for sensing light and transmitting light signals, the circadian clock that oscillates every ~24-hrs, and the genes controlled by the circadian clock to bring about the physiological and behavioral changes. Several genes (Drosophila Clock Per, Tim; mammalian Per1, Per2, Per3, MOP3 and MOP4, and BMAL1) have been linked to rhythmicity or circadian behavior of living organisms. However, very little is known about the mammalian photosensory molecules.||Most recently mammalian homolog of the plant blue-light photoreceptors termed cryptochromes have been identified. Mouse CRY1 and CRY2, are 606aa and 569aa protein, respectively. Cry1 and Cry are specifically expressed in ganglion cell and inner nuclear layers of the mouse retina. CRY1 is expressed at high level in the SCN and oscillates in a circadian manner. Like other genes implicated in circadian mechanism, CRY1 and CRY2 are also expressed in most animal tissues. Therefore, mammalian cryptochromes appears to play an important role in entrainment of the circadian clock.||Applications:|Suitable for use in ELISA.
