There is an exciting increase of evidence that members of the disintegrin and metalloprotease (ADAM) family critically regulate cell adhesion, migration, development and signalling. ADAMs are involved in "ectodomain shedding" of various cell surface proteins such as growth factors, receptors and their ligands, cytokines, and cell adhesion molecules. The regulation of these proteases is complex and still poorly understood. Studies in ADAM knockout mice revealed their partially redundant roles in angiogenesis, neurogenesis, tissue development and cancer. ADAMs usually trigger the first step in regulated intramembrane proteolysis leading to activation of intracellular signalling pathways and the release of functional soluble ectodomains.
越来越多令人兴奋的证据表明,解整合素和金属蛋白酶(ADAM)家族成员对细胞黏附、迁移、发育和信号传导起着关键调节作用。ADAM参与多种细胞表面蛋白的“胞外域脱落”,如生长因子、受体及其配体、细胞因子和细胞黏附分子。这些蛋白酶的调节机制复杂,目前仍知之甚少。对ADAM基因敲除小鼠的研究揭示了它们在血管生成、神经发生、组织发育和癌症中的部分冗余作用。ADAM通常引发调节性膜内蛋白水解的第一步,导致细胞内信号通路激活和功能性可溶性胞外域的释放。
