功能 编辑

穿孔素是一種由细胞毒性T细胞自然殺傷細胞分泌的細胞溶解英语Cytolysis蛋白質。它們會插入靶細胞的細胞膜中,並形成孔隙。穿孔素的MACPF英语MACPF域能夠促使細胞溶解[5]。該域與革蘭氏陽性菌的膽固醇依賴性溶細胞素有一定的同源型[1]

穿孔素在結構上和功能上與補體成分9(C9)具有一些共同點。比如說,穿孔素可以像補體成分9那樣在細胞膜上形成能夠非特異性地裂解多種靶細胞的孔洞。穿孔素是促細胞溶解顆粒中的一種主要促細胞裂解蛋白,在由T細胞和天然殺傷細胞介導的細胞溶解中起關鍵作用[4]。它通過在細胞膜上產生孔洞,從而讓鈣離子大量流入細胞,使得靶細胞啓動細胞膜的修復機制。上述的修復機制可讓穿孔素和顆粒酶進入早期內涵體[6]

臨床意義 编辑

有缺陷的PRF1等位基因純合會導致2型噬血細胞综合癥英语hemophagocytic lymphohistiocytosis,一種罕見的致死性幼年期常染色體隱性遺傳病[4]

相互作用 编辑

數據表明,穿孔素可與鈣網蛋白英语calreticulin發生蛋白質交互作用[7]
