Structural conservation of WEE1 and its role in cell cycle regulation in plants.

ABSTRACT: The WEE1 kinase is ubiquitous in plant development and negatively regulates the cell cycle through phosphorylations. However, analogies with the control of the human cell cycle by tyrosine- (Tyr-) phosphorylation of cyclin-dependent kinases (CDKs) are sometimes questioned. In this in silico study, we assessed the structural conservation of the WEE1 protein in the plant kingdom with a particular focus on agronomically valuable plants, the legume crops. We analyzed the phylogenetic distribution of amino-acid sequences among a large number of plants by Bayesian analysis that highlighted the general conservation of WEE1 proteins. A detailed sequence analysis confirmed the catalytic potential of WEE1 proteins in plants. However, some substitutions of an arginine and a glutamate at the entrance
