Survival Motor Neuron (SMN) is a ~38 kDa protein produced chiefly by the SMN1 gene, located on the telomeric portion of chromosome 5q. A nearly identical centromeric copy of the gene (SMN2) also produces a small amount of full-length SMN protein, but due to a translationally silent C-T transition that results in alternative splicing of the pre-mRNA, most of the resulting SMN is truncated, causing reduced protein stability and lower overall SMN levels. Deletion or mutation of the SMN1 gene results in a reduced level of full-length SMN protein and manifests as a range of neuromuscular phenotypes in humans as the disease spinal muscular atrophy (SMA). SMA is characterized by muscle weakness and atrophy, functional disability and is the most common lethal genetic disease of infants and toddlers. Approximately one in 35 adults is a  carrier of the SMN1 mutation. The incidence of SMA is 1 in 6,000 to 1 in 10,000 live births. SMN protein is present in the cell cytoplasm, and also in the nucleus where it is concentrated in gemstructures associated with Cajal bodies. SMN protein is a constituent of Gemin-containing complexes, and is thought to participate in many aspects of RNA metabolism. SMN complexes have been shown to mediate the assembly of uridine rich small nuclear ribonucleoproteins (snRNPs), which in turn act as critical components of spliceosomes.

 

生存运动神经元(SMN)是一种~38kDa的蛋白质,主要由SMN1基因产生,位于染色体5q的端粒部分。该基因的几乎相同的着丝粒拷贝(SMN2)也产生少量的全长SMN蛋白,但由于翻译沉默的C-T转换导致前mRNA的选择性剪接,大多数产生的SMN被截断,导致蛋白稳定性降低,SMN总水平降低。SMN1基因的缺失或突变导致全长SMN蛋白水平降低,并在人类中表现为一系列神经肌肉表型,如脊髓性肌萎-缩症(SMA)。SMA以肌肉无力和萎-缩、功能残疾为特征,是婴幼儿最常见的致命遗传病。
