摘要:
Shaker类型K+通道在植物钾的吸收、转运及其他生理过程中发挥着重要作用。AKT2/3是Shaker类型K+通道中唯一既主导K+内流,又允许去极化情况下K+渗漏性外流的通道。水稻OsAKT2/3蛋白的生物信息学分析表明,OsAKT2/3蛋白含有K+通道的标志性序列TxxTxGYGD;该基因分子式为C4219H6693N1179O1233S35,理论等电点为664,氨基酸残基组成中亮氨酸残基含量最高;有一定的亲水性,为跨膜蛋白;可能存在31个翻译后修饰位点、5种结构域、52个磷酸化位点,不含信号肽;序列主要构件为α-螺旋和折叠延伸;该蛋白与其他植物的AKT2/3家族成员具有较高的同源性。试验结果为OsAKT2/3基因生理功能的深入研究提供一定依据。
