AP-3(适配器复合物3)介导从晚期高尔基体或早期内体到晚期内体隔室的运输。在哺乳动物中,AP-3的突变导致2型Hermansky-Pudlak综合征、周期性血小板减少症和一种形式的癫痫性脑病。在芽殖酵母中,AP-3将货物直接从高尔基体运送到溶酶体空泡。尽管该途径的重要性和二十年前的发现,AP-3突变体的快速筛选和选择尚未实现。我们现在报告GNSI,一种合成的,遗传编码的报告,允许快速板为基础的评估AP-3功能缺陷,使用显色或生长表型读出。该系统识别AP-3载体囊泡的形成和消耗中的缺陷,并且适用于板阵列和液体分批培养形式中的高通量筛选或选择。已将编码GNSI的附加型和整合型质粒提交至Addgene储存库。
AP-3 (adaptor complex 3) mediates traffic from the late Golgi or early endosomes to late endosomal compartments. In mammals, mutations in AP-3 cause Hermansky-Pudlak Syndrome type 2, cyclic neutropenias, and a form of epileptic encephalopathy. In budding yeast, AP-3 carries cargo directly from the trans-Golgi to the lysosomal vacuole. Despite the pathway’s importance and its discovery two decades ago, rapid screens and selections for AP-3 mutants have not been available. We now report GNSI, a synthetic, genetically encoded reporter that allows rapid plate-based assessment of AP-3 functional deficiency, using either chromogenic or growth phenotype readouts. This system identifies defects in both the formation and consumption of AP-3 carrier vesicles and is adaptable to high-throughput screening or selection in both plate array and liquid batch culture formats. Episomal and integrating plasmids encoding GNSI have been submitted to the Addgene repository.
