Popis: The cell cycle in plants, as in other eukaryotes, is regulated by cyclin-dependent protein kinases (CDKs), which are activated by association with cyclins and can be inhibited by the action of small protein inhibitors (review by Mironov et al., 1999). The first plant inhibitor of CDK, ICK1, was isolated from Arabidopsis thaliana (Wang et al., 1997, 1998). Although ICK1 shares sequence similarity over a short region with the mammalian p27 CDK inhibitor, ICK1 exhibits a unique structure and recombinant ICK1 specifically inhibits plant CDK activity by in vitro histone kinase assays. Three different approaches were used to study the effect of ICK1 in planta: (i) over-expression in Arabidopsis plants, (ii) targeted expression in Brassica plants and (iii) microinjection into Tradescantia stamen hair cells.
