Description

General description

Importin 9 (IPO9) is encoded by the gene mapped to human chromosome 1q32.1. The encoded protein is a molecular transporter and chaperone and is a member of karyopherins super-family. IPO9 has a molecular weight of ~110kDa.

Protein IPO9 exists in two isoforms: a and b in mouse.

Specificity

Anti-Importin 9 (C-terminal) recognizes human Importin 9.

Immunogen

synthetic peptide corresponding to a sequence at the C-terminal part of human Importin 9 conjugated to KLH. The corresponding sequence is identical in mouse and rat.

Application

Anti-Importin 9 (C-terminal) antibody produced in rabbit is suitable for immunoblotting and immunoprecipitation.

Biochem/physiol Actions

Importin 9 (IPO9) promotes transcriptional activity by actively regulating nuclear actin levels. The encoded protein facilitates transport of ribosomal proteins and core histones into the nucleus. Additionally, it acts as an import receptor for c-Jun. Elevated expression of Ipo9 decreased and knockdown of Ipo9 increased basal type I interferon (IFN)-ε expression.

Importins mediate the active transport of cargo molecules through nuclear pore complexes (NPCs). The importins might also protect the cargoes against unnecessary interactions during transit to the nucleus. IPO9 serves as an import factor for protein phosphatase 2A (PP2A) and the hepatocellular carcinoma-associated protein.

Physical form

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. 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.
