How Arabidopsis Receptor-Like Kinase 7 (RLK7) Manifests: Delineating Its Structure and Function

Figure 2

RLK7 functional domain. RLK7 carries a signal peptide, an ectodomain composed of twenty LRRs flanked by an amino (N) terminal cysteine pair and a carboxy (C) terminal cysteine pair, a single transmembrane domain followed by a potential juxtamembrane domain candidate, and a kinase domain. The cysteine pairs are colored in orange. LRRNT and LRRCT are the LRR N-terminal domain and LRR C-terminal domain, respectively. The alignment of the twenty LRR domains is shown above. The gaps represent the spaces introduced for better alignment. The identical and similar amino acids are boxed in blue and green, respectively.
