Survival motor neuron (IPR010304)

Short name: Survival_motor_neuron

Domain relationships



This family consists of several eukaryotic survival motor neuron (SMN) proteins. The Survival of Motor Neurons (SMN) protein, the product of the spinal muscular atrophy-determining gene, is part of a large macromolecular complex (SMN complex) that functions in the assembly of spliceosomal small nuclear ribonucleoproteins (snRNPs). The SMN complex functions as a specificity factor essential for the efficient assembly of Sm proteins on U snRNAs and likely protects cells from illicit, and potentially deleterious, non-specific binding of Sm proteins to RNAs [PMID: 18984161].
