Anti-Snurportin 1 (N-terminal) antibody produced in rabbit

产品说明

一般描述

Snurportin 1 (also known as RNA U transporter 1, SPN1 and SNUPN) comprises three known functional domains: an N-terminal importin-β binding domain (IBB) motif and trimethylguanosine (TMG) cap-binding domain. SNUPN is mapped to human chromosome 15q24.2.

特异性

Anti-Snurportin 1 (N-terminal) recognizes human snurportin 1.

应用

Anti-Snurportin 1 (N-terminal) antibody produced in rabbit may be used in immunoblotting and immunoprecipitation.

生化/生理作用

Snurportin 1 (also known as RNA U transporter 1, SPN1 and SNUPN), mediates nuclear import of 7-methylguanosine (m⁷G) and trimethylguanosine (TMG)-capped uridine-rich small nuclear RNPs (U snRNPs), an important step in the maturation of the spliceosome. The N-terminal importin-β binding domain (IBB) motif, which binds importin β that mediates the interaction with the nuclear pore complex (NPC). The TMG cap-binding domain interacts specifically with m³G-cap but not with m⁷G-cap structures, and an ill-defined region responsible for binding to exportin 1. The active nuclear import, entry of spliceosomal U snRNPs into the nucleus by the importin b/Snurportin1/U snRNP complex does not require RanGTP. Snurportin 1 accumulates in Cajal bodies after import of U2 but not U1 snRNPs.

储存及稳定性

Store at –20 ℃. For continuous use, the product may be stored at 2–8 ℃ for up to one month. For extended storage, freeze in working aliquots at –20 ℃. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
