SNUPN is a nuclear import adaptor protein which is part of the Snurportin family. SNUPN is Localized to the cytoplasm and nucleus and contains an N-terminal IBB domain and a trimethylguanosine (m3G)-cap binding domain. SNUPN binds specifically the terminal 2,2,7-m3G-cap at the 5'' end of U snRNPs and is involved in transport of U snRNPs into the nucleus through an association with Importin Beta.
SNUPN Recombinant Human produced in E.Coli is a single, non-glycosylated polypeptide chain containing 380 amino acids (1-360 a.a.) and having a molecular mass of 43.3 kDa. The SNUPN is fused to 20 amino acid His-Tag at N-terminus and purified by proprietary chromatographic techniques.
UniProt Protein Function: | RNUT1: Functions as an U snRNP-specific nuclear import adapter. Involved in the trimethylguanosine (m3G)-cap-dependent nuclear import of U snRNPs. Binds specifically to the terminal m3G-cap U snRNAs. Belongs to the snurportin family. |
UniProt Protein Details: | Protein type:RNA-binding; Nuclear import Chromosomal Location of Human Ortholog: 15q24.2 Cellular Component: cytosol; nuclear pore Molecular Function:RNA cap binding Biological Process: nuclear import; spliceosomal snRNP biogenesis |
NCBI Summary: | The nuclear import of the spliceosomal snRNPs U1, U2, U4 and U5, is dependent on the presence of a complex nuclear localization signal. The latter is composed of the 5'-2,2,7-terminal trimethylguanosine (m3G) cap structure of the U snRNA and the Sm core domain. The protein encoded by this gene interacts specifically with m3G-cap and functions as an snRNP-specific nuclear import receptor. Alternatively spliced transcript variants encoding the same protein have been identified for this gene. [provided by RefSeq, Jul 2008] |
