Hermansky-Pudlak syndrome (HPS) is a genetically heterogeneous disease involving abnormalities of melanosomes, platelet dense granules and lysosomes. Here we have used positional candidate and transgenic rescue approaches to identify the genes mutated in ruby-eye 2 and ruby-eye mice (ru2 and ru, respectively), two 'mimic' mouse models of HPS. We also show that these genes are orthologs of the genes mutated in individuals with HPS types 5 and 6, respectively, and that their protein products directly interact. Both genes are previously unknown and are found only in higher eukaryotes, and together represent a new class of genes that have evolved in higher organisms to govern the synthesis of highly specialized lysosome-related organelles.
赫尔曼斯基-普德拉克综合征(HPS)是一种基因异质性疾病,涉及黑素小体、血小板致密颗粒和溶酶体的异常。在此,我们采用定位候选基因和转基因拯救方法,来鉴定红宝石眼2型和红宝石眼小鼠(分别为ru2和ru)中发生突变的基因,这两种小鼠是HPS的“模拟”模型。我们还表明,这些基因分别是5型和6型HPS患者中发生突变的基因的直系同源基因,并且它们的蛋白质产物直接相互作用。这两个基因以前均不为人知,且仅在高等真核生物中发现,它们共同代表了一类在高等生物中进化而来的新基因,用于调控高度特化的溶酶体相关细胞器的合成。
