●類泛素蛋白質 (ubiquitin-like proteins) 修飾系統：

本研究室在ubiquitin-proteasome及small ubiquitin-like proteins等蛋白質後轉譯修飾系統的研究方面，著重於探討26S proteasome之19S regulatory particle ATPase (Rpt) 之SUMO化修飾、ubiquitin-specific protease (USP)與NEDD8-specific protease (SENP8) 之基質專一性辨識及作用機制。我們已經鑑定出Rpt分子上被SUMO修飾的胺基酸位置，並且證實Rpt被SUMO修飾後會改變其ATPase活性與在細胞內之位置，亦會影響proteasome之酵素活性；USP2主要是透過辨識ubiquitin與NEDD8之4、12、14與72號之胺基酸序列的保守性不同，而SENP8是透過辨識ubiquitin與NEDD8之51與72號之胺基酸序列的保守性不同，來達到專一性辨識及區別ubiquitin及NEDD8的作用機制，相關研究成果已經發表於PLoS One與Scientific Reports期刊。

 

●免疫學技術之創新性應用：

本研究室長期投入免疫學技術之創新性研究與應用，目前已成功完成薄膜塗佈式西方墨點分析法之研發，經進一步改良後，再搭配真空吸引及毛細管塗佈技術，使抗體用量可減少至傳統方法之百分之一，顯著地降低高單價之抗體的用量，並且能於10分鐘之內完成原本需要三小時才能完成之西方墨點分析實驗，未來將可應用於大量的抗原及抗體篩選實驗，此新穎之薄膜塗佈式西方墨點分析法已發表兩篇研究論文於Analytical Chemistry期刊中，並已取得美國及本國之專利。

 

●新興感染症之相關研究與診斷試劑研發：

本研究室亦積極投入新興感染症之相關研究工作，尤其著重在新型H7N9流感病毒、H5N3/H5N6/H5N8禽流感病毒、茲卡病毒 (Zika virus)、中東呼吸道症候群冠狀病毒 (MERS-CoV) 及2019新型冠狀病毒 (SARS-CoV-2) 之重組蛋白質表現純化與單株抗體的製備。針對上述之多種病毒，我們已成功研發出一系列具有高專一性及病毒中和力的單株抗體，並且皆已運用於快篩技術及分子檢測平台之開發，相關研究成果已發表於國際期刊及進行技轉授權，希望對新興感染症的研究、診斷與治療領域能有所貢獻。
