KPNA2 Protein, Human, Recombinant (His)

Karyopherin Subunit α-2 (KPNA2) belongs to the importin alpha family. KPNA2 is widely expressed in many tissues and contains an N-terminal hydrophilic region, a hydrophobic central region composed of 10 repeats, and a short hydrophilic C-terminus. KPNA2 interacts with the NLSs of DNA helicase Q1 and SV40 T antigen and may be involved in the nuclear transport of proteins. KPNA2 also may play a role in V (D) J recombination. KPNA2 functions in nuclear protein importantly as an adapter protein for nuclear receptor KPNB1.
