We show that importin β3 is essential for the nuclear import of L7. The import is mediated via the multifaceted basic amino acid clusters present in the NH2-region of L7, and is RanGTP-dependent. Using a (EGFP)3 reporter system and a FRAP assay, the role the individual clusters play as a functional NLS has been characterized, and each cluster was found to exhibit a different rate of real time nuclear uptake. We assume that having such a multiple NLS may provide L7 with preferential nuclear uptake.Structured summaryMINT-7992735: Importin beta-3 (uniprotkb:O00410) binds (MI:0407) to L7 (uniprotkb:P18124) by biophysical (MI:0013)MINT-7992687: L7 (uniprotkb:P18124) binds (MI:0407) to Importin beta-3 (uniprotkb:O00410) by filter binding (MI:0049)MINT-7992699: L7 (uniprotkb:P18124) physically interacts (MI:0915) with Importin beta-3 (uniprotkb:O00410) by affinity chromatography technology (MI:0004)MINT-7992718: L7 (uniprotkb:P18124) physically interacts (MI:0915) with RAN (uniprotkb:P62826) by competition binding (MI:0405)MINT-7992671: L7 (uniprotkb:P18124) physically interacts (MI:0915) with Importin beta-3 (uniprotkb:O00410) by pull down (MI:0096)
