摘要: 利用RACE技术,克隆获得了鹅Apolipoprotein A\|1(Apo A1),Fatty acid translocase(CD36)和Diacylglycerol O\|acyltransferase 2(DGAT2)基因的cDNA序列,包括全长的编码区序列(coding sequence,CDS)。结果表明,获得的鹅Apo A1基因的cDNA序列长度为1 106 bp(GenBank accession:KF460562),包括135 bp的5’UTR(untranslated region,UTR)序列,795 bp编码区和176 bp的3’UTR序列,编码265个氨基酸。获得的鹅CD36基因的cDNA序列长度为2 262 bp(GenBank accession:KF460563),包括196 bp的5’UTR序列,1 416 bp编码区和650 bp的3’UTR序列,编码472个氨基酸。获得的鹅DGAT2基因的cDNA序列长度为1 341 bp(GenBank accession:KF460564),包括93 bp的5’UTR序列,1 077 bp编码区和171 bp的3’UTR序列,编码359个氨基酸。同源性分析结果表明,鹅这3个基因cDNA与鸭的同源性最高,达到90%以上,与人等哺乳动物的同源性均较低。

Abstract: The cDNA sequences of goose Apolipoprotein A\|1 (Apo A1), Fatty acid translocase (CD36) and Diacylglycerol O\|acyltransferase 2 (DGAT2) genes including full-length coding sequences (CDS) were cloned by RACE technology. It was shown that the length of goose Apo A1 cDNA was 1 106 bp (GenBank accession: KF460562), which consisted of 135 bp 5’UTR (untranslated region, UTR) sequence, 795 bp coding sequence (encoding 265 amino acids) and 176 bp 3′UTR sequence. The length of goose CD36 cDNA sequence was 2 262 bp (GenBank accession: KF460563), which consisted of 196 bp 5’UTR sequence, 1 416 bp coding sequence and 650 bp 3' UTR sequence, encoding 472 amino acids. The length of cDNA sequence of goose DGAT2 gene was 1 341 bp (GenBank accession: KF460564), consisted of 93 bp 5 ′UTR sequence, 1 077 bp coding sequence and 171 bp 3′ UTR sequence, encoding 359 amino acids. Homology analysis results indicated that goose and duck showed the highest homology (>90%) on the above three genes, while the homology with genes from human and other mammals were relatively low.
