研究主題

實驗室研究方向    [詳細內容]

研究主題:

 

工業酵素的蛋白質結構改良 細菌抗藥性酵素的結構解析與新藥開發、真核細胞內核糖體/訊號辨識粒子/蛋白質轉位體間的交互作用、酵母菌染色質重塑複合體 RSC、果蠅 JAK/STAT 訊息傳遞途徑、鏈黴菌染色體末端蛋白

 

本實驗室目前研究以下蛋白質的結構,並探討其在生物體內的功能:

 

I. 真核細胞內核糖體/訊號辨識粒子/蛋白質轉位體間的交互作用

真核生物核糖體 (Ribosome) 蛋白 L23a 與 L35 (在原核生物內的同源蛋白為 L23 與 L29 ) 在聯繫蛋白質合成、摺疊 (Folding) 與後續運送 (Sorting) 上扮演重大的角色。因為 L23a 與 L35 剛好位在核糖體與監護蛋白 (Chaperones)、訊號辨識粒子 (Signal recognition particle, SRP) 以及蛋白質轉位體 (Translocon) Sec61 相接觸的關鍵地域。雖然近幾年來陸續解出原核核糖蛋白 L23 與 L29 的晶體結構,由於真核核糖蛋白 L23a 與 L35 不論在尺寸與序列上皆和 L23 與 L29 差異極大,十分值得深入探討 L23a 與 L35 如何協助核糖體在真核細胞內同時調控較原核細胞更為複雜的蛋白質合成、摺疊與後續運送。

 

II. 酵母菌染色質重塑複合體 RSC

在真核細胞內,基因組 (Genome) 通常被保護而包裹成染色質 (Chromatin),以防止外來的傷害。但是,當細胞要進行去氧核糖核酸 (DNA) 的轉錄 (Transcription)、複製 (Replication)、傷害修補 (Damage repair) 與重組 (Recombination) 時,染色質會感受到細胞的訊息而改變其構造。染色質重塑複合體 (Chromatin remodeling complexes) 會利用消耗三磷酸腺苷 (ATP) 來改變核仁小體 (Nucleosomes) 的結構與分佈情形,進而重塑染色質的構造。在酵母菌 (Saccharomyces cerevisiae) 細胞內有兩組染色質重塑複合體,分別是 SWI/SNF (SWItch / Sucrose NonFermentable) 與 RSC (Remodelers of the Structure of Chromatin) 複合體。然而兩者中,只有 RSC 複合體對於酵母菌的生存與細胞週期進行是重要且必需的。RSC 複合體內至少含有 16 個蛋白質,其中部分蛋白質成員也同時參與 SWI/SNF 複合體的組成。

 

III. 果蠅 JAK/STAT 訊息傳遞途徑

由 Janus activated kinases (JAKs) 與 Signal transducers and activators of transcription (STATs) 組成的 JAK/STAT 訊息傳遞途徑引導人體內許多重要的生理程序,包含:免疫反應、血球生成、發炎現象以及神經與胚胎的發育。JAK/STAT 訊息傳遞途徑的持續活化也與人類的多種腫瘤的發生,尤其是造血系統惡性腫瘤有關。相較於人,果蠅 (Drosophila melanogaster) 體內有一套簡單的JAK/STAT 訊息傳遞途徑。目前已知其中主要成員包括:三個配體 (Unpaired:Upd、Upd2 與 Upd3)、一個細胞膜上的受器 (Domeless, Dome)、一個 JAK (Hopscotch, Hop) 與一個 STAT (STAT92E)。雖然成員簡單,卻參與了果蠅的體節生成、性別決定、免疫反應、血球生成、眼睛細胞的增生及分化、以及中樞神經、後腸與氣管的發育。

 

IV. 鏈黴菌染色體末端蛋白

鏈黴菌 (Streptomyces) 是一種普遍存在於土壤內的絲狀細菌,屬於革蘭氏陽性菌。鏈黴菌可製造出許多有價值的醫藥品,其中以種類繁多的抗生素最為人所悉。不同於一般細菌具有環形的染色體,鏈黴菌的染色體與質體的構造為直線形。鏈黴菌染色體與質體的端粒 (Telomeres) 均帶有末端蛋白 (Terminal proteins),它們以共價鍵結合上去氧核糖核酸 (DNA) 的 5′ 端。除了保護染色體與質體的端粒構造,目前認為當鏈黴菌染色體利用本身的複製起始點 (The chromosomal origin of replication, OriC) 進行雙向複製後,末端蛋白還擔當引子 (Primer) 來補齊延遲股 (The lagging strand) 上的端點複製問題 (The end replication problem)。
