唾液酸是细胞表面聚糖的组成部分,在细胞间通讯和宿主-病原体相互作用中起重要作用。已知有超过55个基因参与唾液酸生物学,这些基因编码受体、酶和转运蛋白。近10年的研究表明,这些基因中有几个在基因组结构、表达或功能上显示出人类特异性的变化。在本章中,我们将介绍这些人类特有的变化及其对人类进化的可能影响。此外,我们还概述了灵长类动物唾液酸生物学的进化。唾液酸生物学中人类特异性变化的发现是解释人类独特性的遗传基础的一步,这是灵长类动物学的主要活动之一,有助于回答一个跨学科的问题:是什么使我们成为人类?
Sialic acids are components of cell-surface glycans and play important roles in cell–cell communication and host–pathogen interaction. More than 55 genes, encoding receptors, enzymes, and transporters, are known to be involved in sialic acid biology. Nearly 10 years of research have revealed that several of these genes show human-specific changes in genome structure, expression, or function. In this chapter, we introduce these human-specific changes and their possible impact on the human evolution. Also, we give an overview of the evolution of sialic acid biology in primates. The discovery of human-specific changes in sialic acid biology is one step toward explaining the genetic basis of human uniqueness, one of the major activities in primatology, contributing to answering a transdisciplinary question: What makes us human?
