Sumoylation is important for the assembly and function of the SMN complex, which plays a central role in RNA processing. Here the authors show that loss of this posttranslational modification impairs the ability of SMN to correct selective deficits in the sensory-motor circuit of animal models of spinal muscular atrophy.
