A Large Family of Genes That Share Homology withCLAVATA3

Abstract: The receptor kinase superfamily in plants includes a large number of genes, but very little is known about the ligands that bind to these receptors. In the Arabidopsis genome, for example, 340 receptor kinase genes have been identified (The Arabidopsis Genome Initiative, 2000). The proteins encoded by this superfamily share a common overall structure: They are all integral membrane proteins with a single membrane-spanning region and a cytosolic kinase domain. The superfamily can be divided into at least 20 different families based on the structure of the predicted extracellular domains, which differ markedly between families (The Arabidopsis Genome Initiative, 2000; Torii and Clark, 2000). Even within families the extracellular domain can exhibit a high level of variability. For example, within the family of receptor kinases with Leu-rich repeats (LRRs) in their extracellular domains, the number of LRRs present varies from three to more than 20 and the LRRs may be associated with other protein domains.
