Importin alpha 2/KPNA2 Antibody (682208) [Unconjugated]

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 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.
