摘要:

旨在探究桑桑牦牛PFN3基因(Profilin 3)的结构与理化指标,并利用qPCR检测RPL8基因在各组织中的表达情况,为挖掘牦牛PFN3基因的生物学功能提奠定理论基础。以心脏组织cDNA为模板,克隆牦牛PFN3基因的CDS区序列并检测该基因在不同组织中的表达。并使用多种软件和在线工具进行生物信息学分析。结果表明:桑桑牦牛PFN3基因编码区全长为414 bp,共有3个开放阅读框,编码137个氨基酸;通过分析牦牛PFN3蛋白显示,脂肪族系数为101.75,理论等电点9.04,不稳定指数37.22,该蛋白属于稳定的疏水蛋白;该蛋白存在4处潜在磷酸化位点,没有信号肽和跨膜区;氨基酸组成中甘氨酸(Gly)占比最高,为14.6%;亚细胞定位发现,PFN3蛋白在细胞质、细胞核和线粒体内的占比分别为43.5%,30.4%和26.1%;同源性比对发现,桑桑牦牛与野牦牛同源性最近,与非洲疣猪和欧亚野猪的亲缘关系最远;对互作蛋白进行KEGG通路富集分析,发现这些蛋白主要富集在肌动蛋白细胞骨架调控、Rap1信号通路、聚焦黏附、沙门菌感染和肌萎缩侧索硬化等通路中。qPCR结果显示,桑桑牦牛PFN3基因在直肠组织中表达最高,显著高于其他组织,在心脏中表达最低。

Abstract:

The aim of this study was to investigate the structure and physicochemical index of PFN3 gene(Profilin 3)in Sangsang yak,and to detect the expression of RPL8 gene in various tissues by qPCR,so as to lay a theoretical foundation for exploring the biological function of PFN3 gene in Sangsang yak.Using cardiac tissue cDNA as template,we cloned the CDS region of PFN3 gene in yak and detected its expression in different tissues.Bioinformatics analysis is performed using a variety of software and online tools.The results showed that the PFN3 coding region of Sangsang yak was 414 bp in length,with 3 open reading frames encoding 137 amino acids.The analysis of PFN3 protein in yak showed that the aliphatic coefficient was 101.75,the theoretical isoelectric point was 9.04,and the instability index was 37.22,indicating that PFN3 protein was a stable hydrophobic protein.The protein had 4 potential phosphorylation sites and no signal peptide and transmembrane region.Glycine(Gly)accounted for 14.6% of the total amino acids.Subcellular localization showed that PFN3 protein accounted for 43.5%,30.4% and 26.1% in cytoplasm,nucleus and mitochondria,respectively.Homology comparison showed that Sangsang yak had the closest homology with wild yak,and was the most closely related to African warthog and Eurasian boar.KEGG pathway enrichment analysis of interacting proteins showed that these proteins were mainly enriched in actin cytoskeleton regulation,Rap1 signaling pathway,focused adhesion,salmonella infection and amyotrophic lateral sclerosis.qPCR results showed that PFN3 gene expression in Sangsang yak was the highest in rectal tissue,significantly higher than that in other tissues,and the lowest in heart.
