Figure 2

Deduced amino acid sequence of the wheat cysteine-rich repeat receptor-like protein kinase (TaCRK1).
The conserved cysteine-rich repeat (CRR) motif is marked by the open box and located between the signal peptide (indicated by dotted line) and the transmembrane domain (represented by double line). The kinase domain (underlined) follows the transmembrane domain. Roman numbers mark the eleven subdomains conserved in the plant serine/threonine protein kinase family. Arrowheads indicate the three kinase catalytic sites.
