产品介绍 : The protein encoded by this gene belongs to the class-II aminoacyl-tRNA synthetase family. Aminoacyl-tRNA synthetases play critical roles in mRNA translation by charging tRNAs with their cognate amino acids. The encoded protein is a mitochondrial enzyme that specifically aminoacylates alanyl-tRNA. Mutations in this gene are a cause of combined oxidative phosphorylation deficiency 8. [provided by RefSeq, Dec 2011].
Function:
The human alanyl-tRNA synthetase (AlaRS) belongs to a family of tRNA synthases, of the class II enzymes. Class II tRNA synthases evolved early in evolution and are highly conserved. This is reflected by the fact that 498 of the 968-residue polypeptide human AlaRS shares 41% identity witht the E.coli protein. tRNA synthases are the enzymes that interpret the RNA code and attach specific aminoacids to the tRNAs that contain the cognate trinucleotide anticodons. They consist of a catalytic domain which interacts with the amino acid acceptor-T psi C helix of the tRNA, and a second domain which interacts with the rest of the tRNA structure. Alanyl-tRNA synthetase (AlaRS) catalyzes the ligation of alanine with alanyl-tRNA using ATP.

文献和实验和可变环与酶反应 乍看起来,反密码子似乎应该与氨基酸的正确负载有关,对于某些tRNA也确实如此,然而对于大多数tRNA来说,情况并非如此,人们早就知道,当某些tRNA上的反密码子突变后,但它们所携带的氨工酸却没有改变。1988年,候稚明和Schimmel的实验证明丙氨酸tRNA酸分子的氨基酸臂上G3:U70这两个碱基发生突变时则影响到丙氨酰tRNA合成酶的正确识别,说明G3:U70是丙氨酸tRNA分子决定其本质的主要因素。tRNA分子上决定其携带氨基酸的区域叫做副密码子。一种氨基酰tRNA

,从而将目的基因靶向性地导入肿瘤细胞。Khare等将抗人癌胚抗原(CEA)单链抗体编码基因与env基因重组,使反转录病毒将“自杀基因”――一氧化氮合成酶(NOS)靶向导人CEA阳性的肿瘤细胞,并通过过度合成NOS杀死肿瘤细胞。 靶向转移目的基因策略的工作原理 另一个例子是腺病毒。腺病毒载体在感染靶细胞时,首先依靠通过病毒衣壳(capsid)上的纤维蛋白(nber)头部的knob结构域识别并结合靶细胞表面的“柯萨奇病毒和腺病毒受体”(CAR),然后通过衣壳的五邻体
