The survival motor neuron protein in spinal muscular atrophy.
The 38 kDa survival motor neuron (SMN) protein is encoded by two ubiquitously expressed genes: telomeric SMN (SMN(T)) and centromeric SMN (SMN(C)). Mutations in SMN(T), but not SMN(C), cause proximal spinal muscular atrophy (SMA), an autosomal recessive disorder that results in loss of motor neurons. SMN is found in the cytoplasm and nucleus. The nuclear form is located in structures termed gem...
متن کاملSurvival motor neuron protein in motor neurons determines synaptic integrity in spinal muscular atrophy.
The inherited motor neuron disease spinal muscular atrophy (SMA) is caused by deficient expression of survival motor neuron (SMN) protein and results in severe muscle weakness. In SMA mice, synaptic dysfunction of both neuromuscular junctions (NMJs) and central sensorimotor synapses precedes motor neuron cell death. To address whether this synaptic dysfunction is due to SMN deficiency in motor ...
متن کاملDeletions in the survival motor neuron gene in Iranian patients with spinal muscular atrophy.
INTRODUCTION Spinal muscular atrophy (SMA) is a common neuromuscular disorder with progressive paralysis caused by the loss of alpha-motor neurons in the spinal cord. The survival motor neuron (SMN) protein is encoded by 2 genes, SMN1 and SMN2. The most frequent mutation is the biallelic deletion of exon 7 of the SMN1 gene. In SMA, SMN2 cannot compensate for the loss of SMN1, due to the exclusi...
متن کاملHuD interacts with survival motor neuron protein and can rescue spinal muscular atrophy-like neuronal defects.
Spinal muscular atrophy is an autosomal-recessive neuromuscular disease caused by disruption of the survival of motor neuron (SMN) gene, which promotes cytoplasmic assembly of the splicing core machinery. It remains unclear how a deficiency in SMN results in a disorder leading to selective degeneration of lower motor neurons. We report here that SMN interacts with RNA-binding protein HuD in neu...
متن کاملInvestigation of New Morpholino Oligomers to Increase Survival Motor Neuron Protein Levels in Spinal Muscular Atrophy
Spinal muscular atrophy (SMA) is an autosomal-recessive childhood motor neuron disease and the main genetic cause of infant mortality. SMA is caused by deletions or mutations in the survival motor neuron 1 (SMN1) gene, which results in SMN protein deficiency. Only one approved drug has recently become available and allows for the correction of aberrant splicing of the paralogous SMN2 gene by an...
