Recombinant human Snurportin 1/SNUPN protein

SNUPN, also known as KPNBL or RNUT1, is a nuclear import adaptor protein belonging to the Snurportin family. Localizing to the cytoplasm and nucleus, Snurportin-1 contains an N-terminal IBB domain and a trimethylguanosine (m3G) -cap binding domain. It specifically binds the terminal 2, 2, 7-m3G-cap at the 5' end of u snRNPs and functions to transport u snRNPs into the nucleus via an association with Importin beta. Recombinant human Snurportin-1 protien, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography techniques.
