哺乳动物部署了大量的气味受体(OR)来检测和区分大量的气味分子。 OR 在识别的气味结构类型和分子接受范围 (MRR) 的广度上差异很大,一些 OR 识别一小群密切相关的分子,而其他 OR 识别广泛的结构。虽然密切相关的 OR 已被证明具有相似的 MRR,但不太密切相关的 OR 之间的功能关系尚不清楚。我们用不同的气味组筛选了一小群 OR,以确定新的气味剂-OR 配对(不饱和醛和 MOR263-3)。然后我们以各种方式广泛筛选了MOR263-3和一系列与MOR263-3相关的其他MOR。通过系统发育分析相关的 MOR(MOR263 亚家族的其他几个成员)的 MRR 与 MOR263-3 的 MRR 重叠,即使氨基酸同一性低至 48% (MOR263-2)。通过另一种生物信息学分析预测,MOR171-17 与 MOR263-3 功能相关,但氨基酸同一性仅为 39%,具有独特的气味特异性。我们的结果支持使用系统发育分析来预测氨基酸同一性相对较低的 OR 之间的功能关系。
Mammals deploy a large array of odorant receptors (ORs) to detect and distinguish a vast number of odorant molecules. ORs vary widely in the type of odorant structures recognized and in the breadth of molecular receptive range (MRR), with some ORs recognizing a small group of closely related molecules and other ORs recognizing a wide range of structures. While closely related ORs have been shown to have similar MRRs, the functional relationships among less closely related ORs are unclear. We screened a small group of ORs with a diverse odorant panel to identify a new odorant-OR pairing (unsaturated aldehydes and MOR263-3). We then extensively screened MOR263-3 and a series of additional MORs related to MOR263-3 in various ways. MORs related by phylogenetic analysis (several other members of the MOR263 subfamily) had MRRs that overlapped with the MRR of MOR263-3, even with amino acid identity as low as 48% (MOR263-2). MOR171-17, predicted to be functionally related to MOR263-3 by an alternative bioinformatic analysis, but with only 39% amino acid identity, had a distinct odorant specificity. Our results support the use of phylogenetic analysis to predict functional relationships among ORs with relatively low amino acid identity.
