ICK1 is the first member of a family of plant cyclin-dependent kinase (CDK) inhibitors. It has been shown that ICK1 is localized in the nuclei of transgenic Arabidopsis plants. Since cellular localization is important for the functions of cell cycle regulators, a comprehensive analysis was undertaken to identify specific sequences regulating the cellular localization of ICK1. Deletion and site-specific mutants fused to the green fluorescent protein (GFP) were used in transgenic Arabidopsis...[Show more]
