主要内容
全长大肠杆菌组氨基-TRNA合成酶(HARS)已经使用Histrap亲和层析纯化,含有N-末端6x多氨酸标签.Histidyl-TRNA合成酶在其同源转移RNA的3'末端附着氨基酸ATP催化的两步反应。该反应的准确性对于蛋白质合成的整体保真度至关重要。 Hars中的缺陷是eMER综合征3b(USH3B)[MIM:614504]的原因。 USH3B是一种综合征,其特征在于幼儿期间的渐进视力和听力损失。有些患者有所谓的“查尔斯帽综合症”,涉及减少的视力和生动的视觉幻觉。 USH是一种基因上的异质条件,其特征在于视网膜炎与感官耳聋的视网膜炎。在发病和视觉和前庭功能的差异的年龄区分迎来亚瑟综合征1(USH1),映综合征2(USH2)和迎膜综合征3(USH3)。 USH3的特点是后期,进展性听力损失,可变性的心脏功能障碍,以及视网膜炎症状的发作,包括尼克罗缺乏,视野的收缩,以及中枢视力的丧失,通常是克里斯托弗的实验室弗里蒙大学博士,博士。调查员附属物计划的部分。
