Mage-D1是黑素瘤相关抗原MAGE家族Ⅱ类的一个成员,不仅具有该家族所共有的MAGE保守序列MHD结构域,其N端还包含MHD2结构域和WQXPXX多肽重复结构域.与MAGEⅠ类成员不同的是,Mage-D1的功能并不限于胚胎发育、生殖细胞发育和肿瘤发生上.近年研究表明,Mage-D1是p75NTR,UNC5H1,XIAP,Dlx/Msx,Ror2等分子的相互作用蛋白,它在细胞存活、凋亡以及细胞周期和分化中发挥重要调节功能.更为重要的是,MAGE家族Ⅱ类另一个主要成员源自神经分化EC细胞蛋白necdin促进神经元和肌细胞分化的功能,是通过Mage-D1调节Dlx/Msx家族成员的转录活性实现的.本文主要就近年关于Mage-D1结构和生物学功能的研究进行综述和分析.
