摘要

采用RACE PCR方法获得兔颗粒细胞芳香化酶cDNA序列。该cDNA长2.9 kb。前119个核苷酸对应于第一个未翻译的外显子。核苷酸120至1,629对应于编码区(1,509个核苷酸),序列的其余部分是非编码的,包含多聚腺苷化信号。cDNA序列的翻译表明,该蛋白由503个氨基酸组成,与人类芳香化酶相似。分子量为57.4 kDa。家兔芳香化酶氨基酸序列与人类、小鼠、大鼠、牛、猪、鸡、虹鳟和硬骨鱼中已有的芳香化酶序列比对表明,家兔芳香化酶与人类芳香化酶的同源性最高(85%)。

Rapid sequencing of rabbit aromatase cDNA using RACE PCR.

The sequencing of aromatase cDNA from rabbit granulosa cells was obtained by RACE PCR. This cDNA is 2.9 kb long. The first 119 nucleotides correspond to the first untranslated exon. Nucleotides 120 to 1,629 correspond to the coding region (1,509 nucleotides) and the rest of the sequence is non coding and contains a polyadenylation signal. Translation of the cDNA sequence indicates that the protein is composed of 503 amino acids, like in human aromatase. Its molecular weight is 57.4 kDa. The alignment between the rabbit aromatase amino acid sequence and other aromatases already described in the human, mouse, rat, cow, pig, chicken, rainbow trout and teleost fish shows that the rabbit protein exhibits the highest homology with the human one (85%).
