The CTL immune response mediated by MHC I plays an important role in duck anti-TMUV infection. This study reports the expression, purification and crystallization of a complex of duck MHC class I molecules Anpl-UAA*SD, duck β2-microglobulin (Anpl-β2m) and the polypeptide LRKRQLTVL (LRK9) derived from Tembusu virus (TMUV) NS3. The crystal diffraction resolution is 1.50 Å and belongs to the P6₂ space group, and the unit cell parameters are a = 82.468, b = 82.468, c = 112.507. The Matthew's constant is calculated to be 2.32 Å³ Da ⁻¹, and an asymmetric unit contains a complex molecule with a solvent content of 47%. The research lays the foundation for the structure of immune molecules about duck anti-TMUV research.

MHC I介导的CTL免疫应答在鸭抗TMUV感染中起重要作用。这项研究报告了鸭MHC I类分子Anpl -UAA * SD，鸭β2-微球蛋白（Anpl - β2m）和衍生自Tembusu病毒（TMUV）NS3的多肽LRKRQLTVL（LRK9）的复合物的表达，纯化和结晶。晶体衍射分辨率为1.50，属于P 6 ₂空间群，晶胞参数为a  = 82.468，b  = 82.468，c  = 112.507。马修常数经计算为2.32埃³ 沓^-1，不对称单元包含溶剂含量为47％的复杂分子。该研究为鸭抗TMUV研究奠定了免疫分子结构的基础。
