Abstract
We have characterized a novel Arabidopsis gene, designated TMKL1 (for Transmembrane Kinase-Like). The encoded protein is predicted to contain an N-terminal signal peptide, an extracellular domain with seven imperfect leucine-rich repeats, a single hydrophobic transmembrane segment, and a kinase-like intracellular domain which lacks, however, several of the key conserved residues essential for catalytic activity. The TMKL1 protein thus represents a unique and functionally intriguing member of the family of plant proteins related to animal receptor kinases. Northern blot analysis indicates that the TMKL1 gene is transcriptionally active in a variety of organs, and is developmentally regulated during silique maturation. Its possible functions are discussed.
