This entry represents the m3G cap-binding domain of Snurportin1 (SPN1), a nuclear import adaptor for m3G-capped spliceosomal U small nucleoproteins (snRNPs). After capping and assembly, the U snRNPs are transported into the nucleus by SPN1 and importin beta; SPN1 is then returned to the cytoplasm by exportin 1 (CRM1) [1-5].	Domain
