Background

Importin alpha 2, also known as KPNA2 (Karyopherin subunit alpha 2), SRP1a, or 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 beta 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. Over aa 1-132, human Importin alpha 2 shares 94% aa identity with mouse Importin alpha 2.
