Importin alpha 2/KPNA2 in NTera‑2 Human Cell Line. Importin a2/KPNA2 was detected in immersion fixed NTera-2 human testicular embryonic carcinoma cell line using Mouse Anti-Human Importin a2/KPNA2 Monoclonal Antibody (Catalog # MAB62071) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red, upper panel; Catalog # NL007) and counterstained with DAPI (blue, lower panel). Specific staining was localized to nuclei and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: Importin alpha 2/KPNA2

Importin subunit alpha 2, also known as KPNA2 (Karyopherin subunit alpha 2), SRP1a, and RAG1, is a 58-60 kDa member of the Importin alpha family of proteins. It is ubiquitously expressed, and found in both nucleus and cytoplasm. Importin alpha 2 functions as a cargo carrier that transports various complexes from cytoplasm into nucleus. For the MRN DNA repair complex, Importin alpha 2 first binds to NBS1, and then to Importin beta 1, which mediates movement through the nuclear pore. Human Importin alpha 2 is 529 amino acids (aa) in length. It contains an N-terminal IBB/Importin b domain (aa 2-60), ten Armadillo repeats that bind “cargo” (aa 71-496) and two intervening NLS binding sites. There is one splice variant that shows a deletion of aa 72-310, coupled to an 11 aa substitution for aa 389-406. The aminoacid region 1-132 of human Importin alpha 2 shares a 94% homology with mouse Importin alpha 2.
