Survival Motor Neuron (SMN) protein forms the oligomeric core of a multi-protein complex that functions in spliceosomal snRNP biogenesis. It has three highly conserved domains: a short N-terminal segment responsible for binding with high affinity to Gemin2 (a protein involved in snRNP assembly), therefore, called Gemin2-binding domain (G2-BD), a central Tudor domain (Pfam:PF06003) that recognises symmetric dimethylarginine (sDMA) modifications in proteins involved in RNA processing, and a C-terminal domain, referred to as the 'YG-box' domain (Pfam:PF20635) [1,2]. This is the Gemin2-binding domain (G2-BD) of SMN proteins [1,2,3].
