昆虫和脊椎动物的化学信号检测都是由可溶性蛋白介导的，这些蛋白高度集中在嗅觉器官中，它们结合半化学物质并激活特定的化学感受器，其机制仍然很大程度上未知。在信息素合成和释放的结构中经常发现相同的蛋白质，在那里它们可能在溶解和传递环境中的化学信使方面发挥第二种作用。已知在脊椎动物中有一类可溶性多肽，称为气味结合蛋白（OBPs），而在昆虫中已鉴定出两种，OBPs和CSPs（化学感觉蛋白）。尽管它们的名字相同，脊椎动物的obp与昆虫的obp在结构上没有相似性。我们观察到在节肢动物中obp严格限于昆虫，而在甲壳类动物和其他节肢动物中发现了一些CSP家族成员，然而，基于它们非常有限的数量，在化学通信中起作用似乎不太可能。我们在这篇综述中提出的问题是，其他节肢动物是否已经采用了另一类可溶性蛋白来执行昆虫中obp和csp的作用。我们提出Niemann-Pick型C2家族的脂质转运蛋白可能代表可能的候选者，并报告了在不同节肢动物的代表性物种中对其序列的分析结果。
Detection of chemical signals both in insects and in vertebrates is mediated by soluble proteins, highly concentrated in olfactory organs, which bind semiochemicals and activate, with still largely unknown mechanisms, specific chemoreceptors. The same proteins are often found in structures where pheromones are synthesized and released, where they likely perform a second role in solubilizing and delivering chemical messengers in the environment. A single class of soluble polypeptides, called Odorant-Binding Proteins (OBPs) is known in vertebrates, while two have been identified in insects, OBPs and CSPs (Chemosensory Proteins). Despite their common name, OBPs of vertebrates bear no structural similarity with those of insects. We observed that in arthropods OBPs are strictly limited to insects, while a few members of the CSP family have been found in crustacean and other arthropods, where however, based on their very limited numbers, a function in chemical communication seems unlikely. The question we address in this review is whether another class of soluble proteins may have been adopted by other arthropods to perform the role of OBPs and CSPs in insects. We propose that lipid-transporter proteins of the Niemann-Pick type C2 family could represent likely candidates and report the results of an analysis of their sequences in representative species of different arthropods.
