Identification of survival motor neuron as a transcriptional activator-binding protein.
Spinal muscular atrophy (SMA) is an inherited neuro-muscular disease characterized by specific degeneration of spinal cord anterior horn cells and subsequent muscle atrophy. Survival motor neuron ( SMN ), located on chromosome 5q13, is the SMA-determining gene. In the nucleus, SMN is present in large foci called gems, the function of which is not yet known, while cytoplasmic SMN has been implic...
متن کاملSurvival motor neuron protein modulates neuron-specific apoptosis.
Spinal muscular atrophy (SMA) is attributed to mutations in the SMN1 gene, leading to loss of spinal cord motor neurons. The neurotropic Sindbis virus vector system was used to investigate a role for the survival motor neuron (SMN) protein in regulating neuronal apoptosis. Here we show that SMN protects primary neurons and differentiated neuron-like stem cells, but not cultured cell lines from ...
متن کاملSurvival 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...
متن کاملThe survival of motor neuron (SMN) protein interacts with the mRNA-binding protein HuD and regulates localization of poly(A) mRNA in primary motor neuron axons.
Spinal muscular atrophy (SMA) results from reduced levels of the survival of motor neuron (SMN) protein, which has a well characterized function in spliceosomal small nuclear ribonucleoprotein assembly. Currently, it is not understood how deficiency of a housekeeping protein leads to the selective degeneration of spinal cord motor neurons. Numerous studies have shown that SMN is present in neur...
متن کاملThe survival motor neuron protein of Schizosacharomyces pombe. Conservation of survival motor neuron interaction domains in divergent organisms.
Spinal muscular atrophy is a common often lethal neurodegenerative disease resulting from deletions or mutations in the survival motor neuron gene (SMN). SMN is ubiquitously expressed in metazoan cells and plays a role in small nuclear ribonucleoprotein assembly and pre-mRNA splicing. Here we characterize the Schizosacharomyces pombe orthologue of SMN (yeast SMN (ySMN)). We report that the ySMN...
