Background

Importin subunit alpha-5 (KPNA1, Karyopherin subunit alpha 1; also SRP1 beta , NPI-1 and RAG2) is a 65 kDa member of the importin alpha family of proteins. It is ubiquitously expressed, and found in both nucleus and cytoplasm. KPNA1 functions as a cargo carrier that transports various complexes from cytoplasm into nucleus. Two scenarios are possible. First, NLS‑containing cargo molecules bind to KPNA1, which then binds to importin beta ; alternatively, KPNA1 and importin beta initially form a complex that primes KPNA1 for subsequent cargo binding. In either case, importin beta binds to the nuclear pore, facilitating transport into the nucleus. Human KPNA1 is 538 amino acids (aa) in length. It contains an N-terminal IBB/importin beta domain (aa 1‑57), ten Armadillo repeats that bind "cargo" (aa 77‑504) and two intervening NLS binding sites. Over aa 1-132, human KPNA1 shares 97% aa identity with mouse KPNA1.
