Recombinant Human Snurportin 1, His-tagged

• Cat.No.: SNUPN-2746H
• Product Overview: Recombinant human Snurportin-1 protien, fused to His-tag at N-terminus, was expressed inE.coliand purified by using conventional chromatography techniques. MW =43.3 (380aa) confirmed by MALDI-TOF.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Description: 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 β.
