蛋白質泛素化、蛋白質類澱粉化與相關疾病藥物開發

我們的研究主題有二:
(1)蛋白質泛素化之機制探究,及相關連人類疾病之抗病藥物開發
後轉譯修飾在生物體內扮演了相當重要的功能調控角色。 舉凡磷酸修飾、甲基修飾、醣修飾等都是使用小分子直接在蛋白質的特定位置進行修飾。 然而泛素(ubiquitin)標記反應直接採用一個76顆氨基酸的小蛋白質(泛素)修飾在特定蛋白質上面。近半人體內的蛋白質都會被泛素修飾,絕大部分的泛素修飾產物會被帶往細胞內的蛋白酶體處理,如同細胞內的碎紙機把蛋白質絞碎後,回收氨基酸再利用。
我們近年專注於闡明泛素化跟病菌感染之免疫反應,新冠肺炎、登革熱、日本腦炎、感冒、肺結核等感染皆會改變細胞內的泛素化平衡,壓抑免疫力。藉由生物物理學、結構生物學、生物化學及合成生物學的技術,我們致力於闡明感染與泛素化機制,開發抗病菌藥物,提升本身的免疫反應。

(2)蛋白質類澱粉化與神經退化疾病的影響
諸多神經退化疾病都與蛋白質的類澱粉堆疊有關。其中帕金森氏症是僅次於阿茲海默症的神經退化疾病。導致神經退化而得到帕金森氏症的原因眾多,最常見的是腦細胞內的蛋白質 alpha-synuclein的長年性類澱粉化堆疊造成病變。導致alpha-synuclein類澱粉化堆疊的原因包含家族性遺傳、飲食來源、環境因子等,我們專注於探討此蛋白質從無序態逐步轉換成類澱粉化堆疊的過程,藉此找出關鍵的轉換機制,也致力於開發調控轉類澱粉化堆疊方法或藥物。
