病毒是严重依赖宿主细胞过程进行复制的专性寄生虫。通常由病毒编码的少量蛋白质面临选择压力,导致独特结构特性的进化,使每个蛋白质在诸如小基因组大小,高突变率和快速变化的适应性条件等限制下保持其功能。这种进化的一个常见策略是利用小的构建块来产生以多种方式组装的蛋白质寡聚体,从而使蛋白质功能和调节多样化。在这篇综述中,我们讨论了具体的情况下,说明寡聚化是如何被用来产生一个单一的定义的功能状态,通过不同的寡聚状态来调节活性,或通过不同的寡聚状态来产生多种功能形式。
Viruses are obligate parasites that rely heavily on host cellular processes for replication. The small number of proteins typically encoded by a virus is faced with selection pressures that lead to the evolution of distinctive structural properties, allowing each protein to maintain its function under constraints such as small genome size, high mutation rate, and rapidly changing fitness conditions. One common strategy for this evolution is to utilize small building blocks to generate protein oligomers that assemble in multiple ways, thereby diversifying protein function and regulation. In this review, we discuss specific cases that illustrate how oligomerization is used to generate a single defined functional state, to modulate activity via different oligomeric states, or to generate multiple functional forms via different oligomeric states.
