Description
Description
The spliceosomal Sm proteins are common to all spliceosomal small nuclear ribonucleoproteins (snRNPs). Sm proteins assemble in a stepwise manner onto the Sm site element of the U1, U2, U4 and U5 spliceosomal snRNAs forming a ring-shaped core RNP structure. (Adapted from PMID:11226169).
