Transfection of importin α2 into HeLa cells. (A) Schematic illustration of enhanced green fluorescent protein (EGFP)-fused importin α2 proteins used in this transfection analysis. The C-mutant was mutated between 469 and 474 a.a., as indicated. IBB: importin β1-binding, ARM repeats: armadillo repeats. (B) Cellular localization of these encoded proteins in transiently transfected HeLa cells. HeLa cells expressing the EGFP-importin α2 full-length proteins are shown with different exposure times for the same image.
