In this study, we designed a pair of primers based on the sequence of the upstream and downstream of chicken il - 2 gene. about 600 bp chicken il - 2 cdna fragment was cloned from cona - stimulated chicken splenocytes by reverse transcription - polymerase chain reaction ( rt - pcr ) and was subcloned into puc18 vector. recombinant clone was demonstrated by restriction enzyme digestion and dna sequencing. next, we construct recombinant plasmid pproex ? t - il - 2. the cdna of chicken il - 2 gene was subcloned into bamh i / hind iii sites of vector. the recombinant plasmid pproex ? t - il - 2 was transformed into e. coli dh5a and the bacteria was induced with iptg. it was demonstrated by sds - page and western blot that a 18kda protein which was equal to chicken il - 2 protein in molecular weight was expressed in e. coli dh5a. the expression level was up to 30 % of the total bacterial proteins. the purified protein was used to prepare the antibody against chicken il - 2 protein
經酶切鑒定及dna序列測定，該基因為雞il - 2基因，其序列與sundick等報道的完全一致。在此基礎上，我們把雞il - 2基因亞克隆到大腸桿菌原核表達載體pproex ~ （ tm ） ht中，構建重組表達質粒並進行確證性序列測定，重組質粒測序結果表明將編碼雞il - 2成熟蛋白的基因正確地插入到原核表達載體pproex ~ （ tm ） ht的目的位點。重組質粒轉化受體菌dh5後用iptg於37進行誘導培養， sds - page和westernblot分析顯示，表達的雞il - 2融合蛋白分子量約為18kda ，表達的融合蛋白經薄層掃描發現目的蛋白表達量約占菌體蛋白的30 。 -
There is no characteristic in the amino acid sequence 63 - 152 and it is the piece that we want to delete to identify the function of the segment. ie180 gene mutants deleted the 64 - 151 amino acid was amplified by muti - pcr and were cloned by pmdist - vector. the clone plasmids were named pjmp1p3p2. the segment corresponding to the sequence of 1 - 1079 amino acid of the genbank sequence amplified by pcr, its clone plasmids was named pjmp1p2. the segment corresponding to the sequence of 454 - 1079 of genbank sequence amplified by pcr and its clone plasmids is named pjmp6p2 - three clone plasmids and pcdna3 were digested by restriction enzyme bamhi and hind, the gene segment of p1p2, p1p3p2, p6p2 were recycled
本試驗應用dnamis及prosis軟體分別對genbank中登記號為no352564的ie180序列進行了蛋白質序列分析，結果表明其1 - 34段氨基酸序列具有典型helix - turn - helix特徵序列，並且富含酸性氨基酸d及e ，是典型的dna識別序列；富含絲氨酸序列的152 - 409氨基酸序列是一個與激活有關的、潛在的磷酸化位點； 454 - 696氨基酸區域是dna結合域； 64 - 151氨基酸片段沒有明顯的序列特徵；從中可看出ie180蛋白的1 - 1080氨基酸段具有典型的轉錄激活因子結構特徵。
