ADAM17(也称为TACE,肿瘤坏死因子-α转换酶)是一种属于ADAM(去整合素和金属蛋白酶)家族的跨膜蛋白。该基因家族共有约40个成员,其共同特点是具有多个功能域,包括前导肽、金属蛋白酶域、去整合素域、富含半胱氨酸域、跨膜域和胞内域,主要参与细胞表面蛋白的切割(脱落)和细胞间信号传导。ADAM17的主要功能是作为“脱落酶”,通过切割膜结合蛋白的胞外域,释放可溶性分子,从而调控多种信号通路。其最著名的底物是肿瘤坏死因子-α(TNF-α),通过切割前体TNF-α产生具有生物活性的可溶性TNF-α,在炎症和免疫反应中起关键作用。此外,ADAM17还参与表皮生长因子受体(EGFR)配体(如TGF-α和双调蛋白)的脱落,影响细胞增殖、分化和组织修复。ADAM17的活性位点位于其金属蛋白酶域,依赖锌离子进行催化。突变或功能异常可能导致严重疾病,例如ADAM17功能丧失突变与人类炎症性肠病和皮肤异常有关,而过表达则与多种癌症(如乳腺癌、结肠癌)和炎症性疾病(如类风湿性关节炎)相关。ADAM17的过表达会增加TNF-α和EGFR配体的释放,促进炎症反应和肿瘤生长,而降低表达则可能导致发育缺陷、免疫功能受损和伤口愈合延迟。该基因还参与Notch信号通路的调控,影响细胞命运决定。ADAM17的表达受多种因素调控,包括细胞因子、生长因子和活性氧。由于其在炎症和癌症中的重要作用,ADAM17已成为药物开发的潜在靶点,针对其活性的抑制剂正在研究中,用于治疗炎症性疾病和癌症。
This gene encodes a member of the ADAM (a disintegrin and metalloprotease domain) family. Members of this family are membrane-anchored proteins structurally related to snake venom disintegrins, and have been implicated in a variety of biologic processes involving cell-cell and cell-matrix interactions, including fertilization, muscle development, and neurogenesis. The protein encoded by this gene functions as a tumor necrosis factor-alpha converting enzyme; binds mitotic arrest deficient 2 protein; and also plays a prominent role in the activation of the Notch signaling pathway.
