摘要: 动物隐花色素(Cryptochrome)分为I型和II型,对生物钟的调控作用广为人知。I型隐花色素可以感受光信号而介导转录抑制物降解,II型隐花色素不需感受光而直接充当转录抑制物。近期研究发现,动物隐花色素还参与免疫应答和糖代谢,并为果蝇等动物光信号诱导的化学磁感知所必需。对动物隐花色素的进一步研究将增加对动物感知磁场过程的了解,也将帮助开发针对糖尿病等疾病的干预方法。文章重点综述了动物隐花色素的克隆与表达、结构特征、生理功能及作用机制,为这一领域的研究提供参考。

Abstract: Animal cryptochromes are widely known to regulate circadian clock and can be divided into two types. Type I cryptochromes receive light to initiate the degradation of transcriptional inhibitors, whereas type II cryptochromes directly act as light-irresponsive transcriptional inhibitors. Recent studies reveal that animal cryptochromes also have functions in immune response and carbohydrate metabolism, and are required in light-induced chemical magnetoreception in animals like Drosophila. The further researches on animal cryptochromes will improve our understanding of magnetoreception and aid development of therapeutic treatment of diseases such as diabetes. In this review, we summarize the research progresses of animal cryptochromes, with an emphasis on its cloning, expression, and structural and functional studies.
