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 “gem" structures 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.
生存運動神經元(SMN)是一種~38kDa的蛋白質,主要由SMN1基因產生,位于染色體5q的端粒部分。該基因的幾乎相同的著絲粒拷貝(SMN2)也產生少量的全長SMN蛋白,但由于翻譯沉默的C-T轉換導致前mRNA的選擇性剪接,大多數產生的SMN被截斷,導致蛋白穩定性降低,SMN總水平降低。SMN1基因的缺失或突變導致全長SMN蛋白水平降低,并在人類中表現為一系列神經肌肉表型,如脊髓性肌萎-縮癥(SMA)。SMA以肌肉無力和萎-縮、功能殘疾為特征,是嬰幼兒最常見的致命遺傳病。
