Structural basis for snRNA recognition by the double-WD40 repeat domain of Gemin5

Structural basis for snRNA recognition by the double-WD40 repeat domain of Gemin5.

Assembly of the spliceosomal small nuclear ribonucleoparticle (snRNP) core requires the participation of the multisubunit SMN (survival of motor neuron) complex, which contains SMN and several Gemin proteins. The SMN and Gemin2 subunits directly bind Sm proteins, and Gemin5 is required for snRNP biogenesis and has been implicated in snRNA recognition. The RNA sequence required for snRNP assembl...

The right pick: structural basis of snRNA selection by Gemin5.

Macromolecular complexes, rather than individual biopolymers, perform many cellular activities. Faithful assembly of these complexes in vivo is therefore a vital challenge of all cells, and its failure can have fatal consequences. To form functional complexes, cells use elaborate measures to select the "right" components and combine them into working entities. How assembly is achieved at the mo...
