为研究太行山羊SPRN基因的结构及其在不同组织中的表达水平,参考绵羊和牛SPRN基因序列设计引物,应用PCR技术获得了太行山羊 S PR N基因的核苷酸序列,同时对该基因进行生物信息学分析,并通过半定量RT PCR进行组织表达谱分析。结果显示,克隆的太行山羊 S PR N基因序列长度为4237 bp ,含有441 bp的完整开放阅读框,编码146个氨基酸,与绵羊和牛的对应基因序列同源性分别达到95%和93%。 S PR N基因在山羊小脑和大脑中表达水平较高,在睾丸、肠系膜淋巴结和肺脏中表达量很低。
為研究太行山羊SPRN基因的結構及其在不同組織中的錶達水平,參攷綿羊和牛SPRN基因序列設計引物,應用PCR技術穫得瞭太行山羊 S PR N基因的覈苷痠序列,同時對該基因進行生物信息學分析,併通過半定量RT PCR進行組織錶達譜分析。結果顯示,剋隆的太行山羊 S PR N基因序列長度為4237 bp ,含有441 bp的完整開放閱讀框,編碼146箇氨基痠,與綿羊和牛的對應基因序列同源性分彆達到95%和93%。 S PR N基因在山羊小腦和大腦中錶達水平較高,在睪汍、腸繫膜淋巴結和肺髒中錶達量很低。

To investigate the gene structure and tissue expression profile of SPRN gene in Taihang goat ,the primers to amplify SPRN gene are designed based on sheep and cattle se-quences .The genomic sequence of caprine SPRN gene was acquired using PCR technology and tissue expre-ssion profile was analyzed using semi-RT-PCR technology .The bioinformatics analy-sis was done based on caprine SPRN gene sequence .The results showed that the length was 4 237 bp , including the complete open reading frame .The full-length of coding sequence was 441 bp ,enco-ding 146 amino acid .The similarity between goat and sheep or cattle was 95% or 93% respective-ly .The expression profile showed that SPRN mRNA was highly expressed in cerebrum and cere-bellum ,low levels in testis ,mesentic lymph node ,and lung and no mRNA was detected in other ti-ssues .The result of phylogenetic analysis was consistent with the taxonomy .The high expression level of SPRN gene in brain tissue is the important basis for the function research .
