Transcriptional repressor that binds DNA and plays a negative role in regulating microbe-associated molecular patterns-(MAMPs, e.g. flg22, elf18, chitin, and LPS) triggered immunity (PTI) by negatively regulating immune gene expression. Homodimer. Interacts directly with MPK4. EAR motifs are involved in transcriptional repressor activity. Phosphorylated on Thr-189 by MPK4 in response to microbe-associated molecular patterns (MAMPs, e.g. flg22, elf18, chitin, and LPS). This phosphorylation enhances DNA-binding and thus negatively regulates immune gene expression. Enhanced disease resistance to virulent bacterial pathogen infection such as P. syringae pv tomato (Pst) DC3000 and P. syringae pv maculicola (Psm) ES4326 associated with immune gene activation.
