A trimeric CrRLK1L-LLG1 complex genetically modulates SUMM2-mediated autoimmunity

Abstract

MAPK signaling suppresses autoimmunity mediated by the SUMM2 receptor in Arabidopsis. Here Huang et al. show that a trimeric complex consisting of the GPI anchored protein LLG1, and the two receptor-like proteins LET1 and LET2, promotes activation of SUMM2 according to MAPK signaling status.
