Characterization of a gene encoding survival motor neuron (SMN)-related protein, a constituent of the spliceosome complex.
Mutations in the gene encoding the Survival Motor Neuron (SMN) protein are responsible for autosomal recessive proximal spinal muscular atrophy (SMA). SMN orthologues have been identified in the nematode worm Caenorhabditis elegans and the yeast Schizosaccharomyces pombe but, to date, no human paralogues have been described. Here we describe identification and characterization of an SMN-related...
متن کاملThe product of the survival of motor neuron (SMN) gene is a human telomerase-associated protein.
Telomerase is a ribonucleoprotein (RNP) complex that is minimally composed of a protein catalytic subunit, the telomerase reverse transcriptase (TERT), and an RNA component, the telomerase RNA. The survival of motor neuron (SMN) gene codes for a protein involved in the biogenesis of certain RNPs. Here, we report that SMN is a telomerase-associated protein. Using in vitro binding assays and immu...
متن کاملAxonal-SMN (a-SMN), a protein isoform of the survival motor neuron gene, is specifically involved in axonogenesis.
Spinal muscular atrophy (SMA) is an autosomal recessive disease of childhood due to loss of the telomeric survival motor neuron gene, SMN1. The general functions of the main SMN1 protein product, full-length SMN (FL-SMN), do not explain the selective motoneuronal loss of SMA. We identified axonal-SMN (a-SMN), an alternatively spliced SMN form, preferentially encoded by the SMN1 gene in humans. ...
متن کاملInvolvement of survival motor neuron (SMN) protein in cell death.
Infantile spinal muscular atrophy (SMA) is caused by mutations in the survival motor neuron (SMN)1 gene. We investigated the role of human (h) SMN protein on cell death in PC12 and Rat-1 cells. hSMN prolonged cell survival in PC12 cells deprived of trophic support and in Rat-1 cells induced to die by activation of the proto-oncogene c-Myc, to similar magnitude as Bcl-2 or IAP-2. While hSMN was ...
متن کاملCharacterization of the Schizosaccharomyces pombe orthologue of the human survival motor neuron (SMN) protein.
Childhood onset spinal muscular atrophy (SMA) is a common autosomal recessive disorder primarily characterized by the loss of lower alpha motor neurons. The underlying chromosomal defects causing SMA have been found in the survival motor neuron (SMN) gene. SMN has been shown previously to play a role in both snRNP biogenesis and mRNA processing, although direct evidence for the relationship bet...
