BasicMechanismsofSUMOylation
Like ubiquitin, SUMO (small ubiquitin-related modifier) proteins are small protein tags that are conjugated to proteins to modify their function. The ubiquitin system tags proteins for degradation by the proteosome (see Proteosome pathway) but SUMO conjugation has a range of other functions, stabilizing some proteins and altering their subcellular localization. Sumoylation may also influence ubiquitination and protei......阅读全文

Nature：SUMOylation水平与细菌感染
在感染过程中，食源性病原体“单核细胞增生李斯特菌”能利用宿主细胞的大量功能，包括涉及泛素化和磷酸化的、专门修饰关键蛋白活性的转录后修饰。致病细菌对被称为“SUMOylation”的泛素样修饰（真核细胞中一个重要过程）()的效应在很大程度上仍不清楚。现在，对被“单核细胞增生李斯特菌”感染的人类细胞和
