组织蛋白酶F(英文:Cathepsin F)是一种在人体中由CTSF基因编码的蛋白质[6][7][8]

木瓜样蛋白酶是半胱氨酸蛋白酶家族,代表溶酶体蛋白水解系统的主要成分。通常,组织蛋白酶包含一个信号肽,然后是一个前肽,再然后是一个催化活性成熟区。组织蛋白酶F前体非常长的(251个氨基酸残基)前区包含一个与组织蛋白酶L样酶的前段相似的C端结构域、一个50个残基的柔性连接肽和N端结构域预计采用胱抑素样折叠组织蛋白酶F前区在木瓜蛋白酶家族半胱氨酸蛋白酶中是独一无二的,因为它包含这个额外的N端片段,预计与胱抑素超家族的半胱氨酸蛋白酶抑制剂具有结构相似性。这种胱抑素样结构域包含一些已知对抑制活性很重要的元素。CTSF编码预测的484个氨基酸的蛋白质,其中包含19个残基信号肽。组织蛋白酶F含有五个潜在的N-连接糖基化位点,它可能通过甘露糖6-磷酸受体途径靶向内体/溶酶体区室。组织蛋白酶F基因普遍表达,它定位于染色体11q13,接近编码组织蛋白酶W的基因。[8]

泰国肝吸虫的免疫诊断

[编辑]

组织蛋白酶F可用作测试泰国肝吸虫造成的疾病的替代方法。[9]近年来,泰国肝吸虫的诊断一直通过大便检查来完成,被认为是“金标准”方法。然而,基于粪便的诊断可能是不可靠的[10],尽管它是一种非侵入性方法。进行的实验表明,通过使用重组DNA技术和组织蛋白酶F半胱氨酸蛋白酶,可以产生更可靠的结果。

组织蛋白酶F在虾夷盘扇贝中的表达

[编辑]

最近的实验表明在虾夷盘扇贝中发现了组织蛋白酶F。[11]在虾夷盘扇贝的各个胚胎发育阶段鉴定组织蛋白酶F基因具有重要意义。组织蛋白酶F基因在先天免疫反应中具有重要作用。虾夷盘扇贝一直因细菌性疾病而遭受高死亡率。组织蛋白酶F的发现可以领导进一步的研究和解决虾夷盘扇贝死亡率问题的方法。
