Direct Interaction of the Spinal Muscular Atrophy Disease Protein SMN with the Small Nucleolar RNA-associated Protein Fibrillarin

Abstract excerpt

Disruption of the survival motor neuron (SMN) gene leads to selective loss of spinal motor neurons, resulting in the fatal human neurodegenerative disorder spinal muscular atrophy (SMA). SMN has been shown to function in spliceosomal small nuclear ribonucleoprotein (snRNP) biogenesis and pre-mRNA splicing. We have demonstrated that SMN also interacts with fibrillarin, a highly conserved nucleolar protein that is...
