Highly expressed in seedlings and leaves. Lower expression in roots, stems, flowers and siliques. Detected in the vascular tissues of roots, in the trichomes of young rosettes leaves and hydathodes, in the floral abscission zones, in filament apex and stomata cells of anthers, in inflorescence stems and in sepals. By not induced by salicylic acid. The protein kinase domain is predicted to be catalytically inactive. No visible phenotype. Probably due to the redundancy with other receptor-like kinases. Belongs to the protein kinase superfamily.
