摘要:
蛋白质N末端乙酰化修饰是真核生物中重要的蛋白质修饰类型,该修饰由一系列进化保守的N末端乙酰转移酶催化完成。为了探究N末端乙酰转移酶Naa20在植物发育进程中的作用,对拟南芥Naa20基因的突变体进行表型观察,发现naa20突变体相较于野生型表现出营养生长阶段幼年态向成年态转变的提前,并且开花时间也提前。转基因互补分析表明,naa20突变体发育时相转变提前是由于Naa20基因表达缺失引起的。遗传分析表明,naa20 hst双重突变体表现出与hst单突变体相似的幼年态向成年态转变提前和开花时间提前的表型。酵母双杂交试验表明,Naa20蛋白与Naa25蛋白具有直接的相互作用。以上结果表明,Naa20与Naa25存在于同一个复合体,通过下游调控HST进而抑制植物发育时相的转变,在植物营养生长时期转变和生殖生长转变过程中发挥了重要的作用。
