Cf-RLP conserved motifs. A, Alignment of the B domain of Cf-RLPs to the N terminus of PGIP. 1OGQA is the Protein Data Bank identifier of the solved PGIP structure. Columns with highly conserved amino acids are highlighted in gray. Conserved Cys are marked with asterisks. B, Alignment of the C2 region of Cf-RLPs highlighting the Yx(n)KG motif. The conserved residues are indicated with asterisks and the columns are shaded as in A. C, Alignment of the TM regions of functionally characterized RLPs, RLKs, and PDOs that contain GXXXG-type motifs. The conserved Gly (or Ser) in the GXXXG-type motifs are highlighted in gray and are marked with asterisks.
