U11 base pairs with the 5’ splice sites; U12 base pairs with the branch point sequence near the 3’ splice site; and U4atac and U6atac provide analogous functions during the spliceosome assembly and activation of the spliceosome.

Each snRNP contains a single snRNA (100-300 nt) and several (20) proteins. The U4 and U6 snRNPs are usually found together as a di-snRNP (U4/U6) particle.
