Arabidopsis thaliana receptor-like protein AtRLP23 associates with the receptor-like kinase AtSOBIR1.

ABSTRACT: Plants employ a large number of receptors localizing to the cell surface to sense extracellular signals. Receptor-like proteins (RLPs) form an important group of such trans-membrane receptors, containing an extracellular domain which is involved in signal perception and a short cytoplasmic domain. In contrast to receptor-like kinases (RLKs), RLPs lack a cytoplasmic kinase domain. How intracellular signaling is triggered downstream of RLPs upon perception of an extracellular signal, is therefore still poorly understood. Recently, the RLK SOBIR1 (Suppressor Of BIR1-1) was identified as an essential regulatory RLK of various RLPs involved in plant immunity against fungal pathogens. (1) Given that SOBIR1 appears to be a crucial component of RLP-containing complexes, we aimed to identify additi
