title: Generation of a rat monoclonal antibody specific for importin alpha3/Qip1.
abstract: Importin alpha, which mediates the nuclear import of nuclear localization signal (NLS)-containing proteins, is a member of nuclear transport factors. Importin alpha binds directly NLS and functions as an adapter for accessing the importin beta-dependent import pathway. To date, several isoforms of importin alpha have been identified and classified into three subfamilies in higher eukaryotes. In this study, we report on the production of a rat monoclonal antibody (MAb) against importin alpha3/Qip1, a member of the importin alpha family, using a rat medial iliac lymph node method. The MAb 3D10 produced, reacted with both recombinant and endogenous importin alpha 3/Qip1. Immunoblotting analysis revealed that MAb 3D10 exclusively recognizes importin alpha3/Qip1 among members of the importin alpha family, in various mammalian cells.
