Belongs to the RLP family. Could be the product of a pseudogene. In strain cv. Columbia, a naturally occurring variation results in the deletion of 35 amino acids in the middle part of the protein. Lacks part of the extracellular leucine-rich repeats that are required for the specificity of the elicitor protein recognition. Was originally thought to correspond to two different genes At1g54470 and At1g54475. Was originally thought to correspond to two different genes At1g54470 and At1g54475.
