我们已经确定了天冬氨酸蛋白酶组织蛋白酶D作为一种新的细胞内靶蛋白的脂质第二信使神经酰胺。神经酰胺特异性结合并诱导CTSD蛋白水解活性。来自尼曼-匹克患者的A-SMase缺陷细胞显示通过用A-SMase cDNA转染重建的CTSD活性降低。来自A-神经酰胺酶缺陷型法伯患者的细胞中的神经酰胺蓄积与增强的CTSD活性相关。这些发现表明A-SMase衍生的神经酰胺靶向内溶酶体CTSD。
We have identified the aspartic protease cathepsin D as a novel intracellular target protein for the lipid second messenger ceramide. Ceramide specifically binds to and induces CTSD proteolytic activity. A-SMase deficient cells derived from Niemann-Pick patients show decreased CTSD activity that was reconstituted by transfection with A-SMase cDNA. Ceramide accumulation in cells derived from A-ceramidase defective Farber patients correlates with enhanced CTSD activity. These findings suggest that A-SMase-derived ceramide targets endolysosomal CTSD.
