MATR3 is an RNA- and DNA-binding protein that interacts with TDP-43, a disease protein linked to amyotrophic lateral sclerosis (ALS) and frontotemporal dementia. Using exome sequencing, we identified mutations in MATR3 in ALS kindreds. We also observed MATR3 pathology in ALS-affected spinal cords with and without MATR3 mutations. Our data provide more evidence supporting the role of aberrant RNA processing in motor neuron degeneration.
MATR3 是一种 RNA 和 DNA 结合蛋白，与 TDP-43 相互作用，TDP-43 是一种与肌萎缩侧索硬化症 (ALS) 和额颞叶痴呆相关的疾病蛋白。使用外显子组测序，我们在 ALS 家系中发现了 MATR3 突变。我们还观察到有和没有 MATR3 突变的 ALS 受累脊髓中的 MATR3 病理学。我们的数据提供了更多证据支持异常 RNA 处理在运动神经元退化中的作用。
