微孢子虫家蚕微粒子虫(Nosema bombycis)是家蚕(Bombyx mori)的一种专性细胞内寄生虫,在进化过程中失去了完整的三羧酸循环和线粒体,但保留了完整的糖酵解途径。家蚕微粒子虫己糖激酶(NbHK)不仅是糖酵解的一种限速酶,也是一种分泌蛋白。间接免疫荧光分析以及在BmN细胞中过表达的重组HK表明,在裂殖体阶段,NbHK定位于宿主细胞的细胞核和细胞质。当家蚕微粒子虫成熟时,NbHK倾向于聚集在宿主细胞的细胞核。此外,NbHK的转录图谱表明它在家蚕微粒子虫的增殖阶段发挥作用。对NbHK的敲低有效抑制了家蚕微粒子虫的增殖,这表明NbHK是寄生虫控制其宿主的一种重要蛋白质。
The microsporidian Nosema bombycis is an obligate intracellular parasite of Bombyx mori, that lost its intact tricarboxylic acid cycle and mitochondria during evolution but retained its intact glycolysis pathway. N. bombycis hexokinase (NbHK) is not only a rate-limiting enzyme of glycolysis but also a secretory protein. Indirect immunofluorescence assays and recombinant HK overexpressed in BmN cells showed that NbHK localized in the nucleus and cytoplasm of host cell during the meront stage. When N. bombycis matured, NbHK tended to concentrate at the nuclei of host cells. Furthermore, the transcriptional profile of NbHK implied it functioned during N. bombycis’ proliferation stages. A knock-down of NbHK effectively suppressed the proliferation of N. bombycis indicating that NbHK is an important protein for parasite to control its host.
