UL21 is a conserved protein in the tegument of alphaherpesviruses and has multiple important albeit poorly understood functions in viral replication and pathogenesis. To provide a roadmap for exploration of the multiple roles of UL21, we determined the crystal structure of its conserved N-terminal domain from herpes simplex virus 1 to 2.0-Å resolution, which revealed a novel sail-like protein fold. Evolutionarily conserved surface patches highlight residues of potential importance for future targeting by mutagenesis.
UL21是α疱疹病毒被膜中的一种保守蛋白,在病毒复制和发病机制中具有多种重要但了解甚少的功能。为了提供探索UL21多种作用的路线图,我们确定了单纯疱疹病毒1 UL21保守N端结构域的晶体结构,分辨率达到2.0 Å,揭示了一种新型的帆状蛋白折叠结构。进化上保守的表面区域突出了通过诱变进行未来靶向的潜在重要残基。
