Anti-Importin α antibody, Mouse monoclonal，200UL，I1784-200UL，Sigma

General description

Monoclonal Anti-Importin α (mouse IgG2b isotype) is derived from the hybridoma IM-75 produced by the fusion of mouse myeloma cells (NS1 cells), and splenocytes from BALB/c mice, immunized with recombinant human importin α. The Importin α family of proteins is comprised of three subfamilies based on amino acid sequence similarity: SRP1-like subfamily (containing the SRP1, importin α5, α6 and α7), Rch1-like subfamily (containing Rch1, pendulin, importin α2), and α3/Qip1-like subfamily (containing α4).

Immunogen

recombinant human importin α.

Application

Anti-Importin α antibody, Mouse monoclonal has been used:

• enzyme linked immunosorbent assay (ELISA)
• immunoblotting
• immunoprecipitation
• immunocytochemistry

Biochem/physiol Actions

The gene KPNA4 (karyopherin subunit α 4) encodes a 16kDa protein, also referred to as importin α 3 belonging to the family of karyopherins (designated KPNA1 to KPNA4). It participates in the recognition of NLS (nuclear localization sequence) sites and dock NLS-containing proteins destined for transport into the nuclear pore complex. It binds to translocon and participates in the sorting of INM (inner nuclear membrane)-directed integral membrane proteins. It associates with nucleoporins and functions in cargo-translocation across the nuclear membrane. Each KPNA contains an N-terminal repeat domain called the importin β binding site that binds to KPNB1, which in turn directs each KPNA/cargo complex through the nuclear pore. The encoded shuttling protein also functions in NF (nuclear factor)-κB nuclear translocation.
