  Abstract

Aurora kinases play a key role in chromosome segregation and cytokinesis. In plants, three Aurora kinases (AtAUR1-3) have been identified in Arabidopsis thaliana. Here, we report an AtAUR2 splicing variant (AtAUR2S), which lacking the fourth exon which encodes a part of the kinase domain of AtAUR2. AtAUR2S was shown to have lost its kinase activity to phosphorylate histone H3 at Ser10; however, it maintained its ability to bind to histone H3. The localization pattern of AtAUR2S was the same as that of AtAUR2. The findings suggest that AtAUR2S affects cell division by competing with AtAUR2.

Keywords: alternative splicing - Arabidopsis thaliana - Aurora kinase - histone H3

The nucleotide sequence reported in this paper has been submitted to the DDBJ/EMBL/GenBank databases under the accession number AB279605 [GenBank] .
