A cDNA corresponding to canine IL-2 has been isolated and sequenced. The cDNA was synthesised using RT-PCR, with oligonucleotide primers designed from conserved regions of published IL-2 sequences. The cDNA encodes a predicted full length IL-2 protein of 155 amino-acids. At the nucleic acid level, the canine cDNA shows 92, 88, 88, 82 and 74% homology to published sequences of feline, human, equine, bovine and murine IL-2, respectively. The derived protein shows 90, 86, 85, 76 and 75% similarity to feline, human, equine, murine and bovine IL-2 homologs.
已分离并测序了与犬白细胞介素-2(IL-2)对应的cDNA。使用RT-PCR合成该cDNA,寡核苷酸引物是根据已发表的IL-2序列的保守区域设计的。该cDNA编码一个预测的全长155个氨基酸的IL-2蛋白。在核酸水平上,犬cDNA与已发表的猫、人、马、牛和小鼠IL-2序列的同源性分别为92%、88%、88%、82%和74%。推导的蛋白与猫、人、马、小鼠和牛的IL-2同源物的相似性分别为90%、86%、85%、76%和75%。
