摘  要:
[目的]研究马氏珠母贝(Pinctada martensii)β2肾上腺素能受体(Pmβ2AR)的生物学功能.[方法]利用cDNA末端快速扩增技术(RACE)克隆获得Pmβ2AR基因的cDNA的全长序列并对其序列特征进行分析,实时荧光定量技术(qRT-PCR)检测马氏珠母贝不同组织中 β2AR基因mRNA的表达水平.[结果与结论]Pmβ2AR的cDNA全长2426 bp,包括开放阅读框(ORF)2091 bp,编码696个氨基酸,5′UTR长144 bp,3′UTR长191 bp,预测分子质量79.0 ku,理论等电点9.18,多重序列比对结果发现 β2AR在不同物种间的保守性较高.软件分析结果显示Pmβ2AR的氨基酸序列具有7个典型的跨膜结构域.qRT-PCR结果表明,Pmβ2AR基因在各组织中均有表达,在鳃中表达量最高,在肝胰腺和性腺中表达量也较高.

摘  要:
【Objective】To study the biological function of Pinctada martensii β2 AR(Pmβ2 AR).【Methods】The full length of Pmβ2 AR gene was cloned using rapid amplification of cDNA end technology(RACE)and its sequence characteristics were analyzed. Meanwhile, the expression of β2 AR m RNA in different tissues of P. f. martensii was detected by Real-time PCR(RT-PCR).【Result and conclusion】It shows that the total length of Pmβ2 AR gene was 2 426 bp, including 2 091 bp of the open reading frame(ORF)which encoded 696 amino acids, a 5′ untranslated region of 144 bp and a 3′untranslated region of 191 bp. The predicted molecular weight was 79.0 ku, and the isoelectric point was 9.18. Multiple sequence alignment results showed that β2 AR was conservative among different species. Domain analysis showed that the amino acid sequence of Pmβ2 AR had 7 typical transmembrane domains. In addition, qRT-PCR indicated that Pmβ2 AR was expressed in all the detected tissues, and the highest expression level was in the gills, followed by hepatopancreas and gonads.
