WebMar 25, 2005 · A macromolecular complex containing survival of motor neurons (SMN), the spinal muscular atrophy protein, and Gemin2–7 interacts with Sm proteins and snRNAs to carry out the assembly of these components into spliceosomal small nuclear ribonucleoproteins (snRNPs). WebOne of the best-studied examples of such a chaperone is the survival motor neuron (SMN) protein, the disease gene in spinal muscular atrophy (SMA). SMN is part of a macromolecular protein complex and catalyzes the assembly of a heptameric core of Sm proteins onto small nuclear RNAs (snRNAs) to form spliceosomal snRNPs required for …
