The importin-β binding domain of snurportin1 is responsible for the Ran- and energy-independent nuclear import of spliceosomal U snRNPs in vitro

The nuclear localization signal (NLS) of spliceosomal U snRNPs is composed of the U snRNA's 2,2,7-trimethyl-guanosine (m(3)G)-cap and the Sm core domain. The m(3)G-cap is specifically bound by snurportin1, which contains an NH(2)-terminal importin-β binding (IBB) domain and a COOH-terminal m(3)...
