摘要: 为研究牦牛PPP1R11基因的结构和功能,及在8个不同组织中的表达规律,以帕米尔牦牛睾丸组织cDNA为模板,使用PCR技术克隆帕米尔牦牛PPP1R11基因CDS区序列,并进行生物信息学分析,PPP1R11基因在帕米尔牦牛8个组织中的表达水平通过实时荧光定量PCR (RT-qPCR)进行测定。结果表明,帕米尔牦牛PPP1R11基因CDS区全长324 bp,编码107个氨基酸。同源性对比结果显示,帕米尔牦牛与野牦牛的相似性最高(100%),与小家鼠的相似性最低(84.6%)。生物信息学分析结果表明,PPP1R11 蛋白分子式为C503H803N163O164S8,原子总数为1 641,不稳定指数和总平均亲水指数分别为65.91和-1.385,为亲水性蛋白;PPP1R11蛋白不具有信号肽和跨膜结构,主要定位在细胞核中;且该蛋白有1个糖基化位点和19处潜在的磷酸化位点;蛋白的二级结构以无规则卷曲为主,与PPP1R7、PPP1CA和NSFL1C等蛋白存在主要相互作用。RT-qPCR分析表明,PPP1R11基因在帕米尔牦牛心脏、肌肉、脂肪、脾脏、肝脏、胰脏、肾脏和睾丸这8个组织中存在差异性表达,相较于其他7种组织,PPP1R11在睾丸中的表达显著上调。

Abstract:

To investigate the structure and function of the PPP1R11 gene in yaks,along with its expression pattern in eight distinct tissues,cDNA from the testicular tissue of Pamir yaks was utilized as the template,the CDS region sequence of the PPP1R11 gene in Pamir yaks was cloned via PCR technology,followed by bioinformatics analysis.The expression level of the PPP1R11 gene in eight tissues of the Pamir yak was determined using Real-time Fluorescence Quantitative PCR(RT-qPCR).The results showed that the coding sequence(CDS region)of PPP1R11 gene in Pamir yak was 324 bp and encoded 107 amino acids.The homology comparison showed that Pamir yak had the highest similarity with Bos mutus(100%)and the lowest similarity with Mus musculus(84.6%).The results of bioinformatics analysis showed that the molecular formula of PPP1R11 protein was C503H803N163O164S8,the total number of atoms was 1 641,the instability index and the total average hydrophilic index were 65.91 and -1.385,respectively.PPP1R11 protein had no signal peptide and transmembrane structure,and was mainly located in the nucleus.The protein had one glycosylation site and 19 potential phosphorylation sites.The secondary structure of the protein was mainly random curling,and it mainly interacted with PPP1R7,PPP1CA and NSFL1C.The RT-qPCR results showed that PPP1R11 gene was expressed differently in heart,muscle,fat,spleen,liver,pancreas,kidney and testis of Pamir yak,and the expression level of PPP1R11 gene was significantly higher in testis than in the other seven tissues.
