Function

Cryptochrome (Cry) is a flavoprotein associated with the biological clock function. In Drosophila melanogaster it is also involved in blue-light photoreception^[1].

Cryptochrome-1 is a circadian clock repressor^[2].
Cryptochrome-2 is a blue light receptor involved in flowering induction^[3].
Cryptochrome-4 is magnetically sensitive and thus is involved in night migration of birds^[4]. For details see Cryptochrome 4.

Disease

The absence of Cry resulting in the lack of functional clock system leads to elevated proinflammatory cytokine activation and thus to increase incidence of chronic diseases such as diabetes, obesity and also cancer^[5].
