摘要 真核生物的CK1十分保守,从酵母和动物中的研究来看,CK1具有非常重要的功能,参与调控各个方面的生命活动。在植物中CK1家族大大倍增,如双子叶植物拟南芥有17个成员,单子叶植物水稻有15个成员,但是相关的功能报道比较少。中国科学院上海生命科学研究院植物生理生态研究所薛红卫研究组曾发现CK1在水稻中参与了油菜素内酯和赤霉素等激素信号响应过程。最近,他们以模式植物拟南芥为系统,采用遗传学和生物化学的手段,发现CK1的两个成员CK1.3和CK1.4可以以蓝光诱导的方式磷酸化蓝光受体CRY2,并促进其降解。这项工作不仅鉴定出CK1是蓝光信号途径的重要组分,并且阐明了隐花色素信号转导中一种信号消减机制,大大增进了对于植物中蓝光信号转导机制的理解和CK1功能的认识。
