A Functional Interaction between the Survival Motor Neuron Complex and RNA Polymerase II

Abstract excerpt

The survival motor neuron (SMN) protein, the protein product of the spinal muscular atrophy (SMA) disease gene, plays a role in the assembly and regeneration of small nuclear ribonucleoproteins (snRNPs) and spliceosomes. By nanoelectrospray mass spectrometry, we identified RNA helicase A (RHA) as an SMN complex-associated protein. RHA is a DEAH box RNA helicase which binds RNA polymerase II (pol II) and...
