这个基因属于一组与微卫星扩张疾病相关的基因,这类神经系统和神经肌肉疾病是由短重复DNA片段扩张引起的。这个基因编码的蛋白质在N端附近有两个球形结构域,其中一个含有氯素介导的跨高尔基信号和内质网出口信号。该编码的细胞质蛋白定位在内质网和质膜上,参与内吞作用,并调节mTOR信号,修改核糖体翻译和线粒体功能。蛋白质的N端区域含有一个14-31个残基的聚谷氨酰胺轨道,在病理状态下可以扩张到32-200个残基。这个轨道的中等长度扩张增加对肌萎缩侧索硬化的易感性,而该轨道的长度扩张导致脊髓小脑共济失调-2,这是一种常染色体显性遗传的神经退行性疾病。全基因组关联研究表明,这个基因的失功能突变可能与I型糖尿病、肥胖和高血压的易感性相关。可变剪接导致多个转录变异体。[RefSeq,2016年11月提供]
