Survival motor neuron: motor neuron insurance for a whole lifespan?
The SMN (survival motor neuron) gene plays an important role in ontogenesis and its dysfunction leads to immatu-rity of skeletal muscles and motor neurons in the spinal cord. As a result of SMN mutations the affected cells die and clinical symptoms of spinal muscular atrophy (SMA) develop. Physiologically, SMN together with gemins is part of a multiprotein complex of particular importance to mo...

15 صفحه اولNeuromuscular defects in a Drosophila survival motor neuron gene mutant.
Autosomal recessive spinal muscular atrophy (SMA) is linked to mutations in the survival motor neuron (SMN) gene. The SMN protein has been implicated at several levels of mRNA biogenesis and is expressed ubiquitously. Studies in various model organisms have shown that the loss of function of the SMN gene leads to embryonic lethality. The human contains two genes encoding for SMN protein and in ...
متن کاملFunctional Diversification of Motor Neuron-specific Isl1 Enhancers during Evolution
Functional diversification of motor neurons has occurred in order to selectively control the movements of different body parts including head, trunk and limbs. Here we report that transcription of Isl1, a major gene necessary for motor neuron identity, is controlled by two enhancers, CREST1 (E1) and CREST2 (E2) that allow selective gene expression of Isl1 in motor neurons. Introduction of GFP r...
متن کاملOverexpression of survival motor neuron improves neuromuscular function and motor neuron survival in mutant SOD1 mice
Spinal muscular atrophy results from diminished levels of survival motor neuron (SMN) protein in spinal motor neurons. Low levels of SMN also occur in models of amyotrophic lateral sclerosis (ALS) caused by mutant superoxide dismutase 1 (SOD1) and genetic reduction of SMN levels exacerbates the phenotype of transgenic SOD1(G93A) mice. Here, we demonstrate that SMN protein is significantly reduc...
