We report here the isolation of the Arabidopsis thaliana gene AtK-1. The predicted protein sequence of AtK-1 show 70% identity to the Arabidopsis ASK and alfalfa MsK kinases that are homologs of the Drosophila shaggy and rat GSK-3 serine/threonine protein kinases playing an important role in signal transduction processes in animals. Northern analysis of different organs revealed exclusive expression in inflorescences suggesting an involvement of the AtK-1 kinase in reproduction-specific processes.
