Non-TIFY functional repressor of jasmonate (JA)-mediated growth and defense responses. Intrinsically resistant to JA-induced turnover, probably due to the absence of the canonical degron that strongly interacts with COI1 in the presence of JA-Ile in the TIFY/JAZ proteins. Monomer. Lack of homodimerization, and very weak or no interaction with AFPH2/NINJA and other JAZ proteins. Interacts (via EAR motif) with TPL. Interacts (via jas motif) with MYC2. Up-regulated by mechanical wounding, and methyl jasmonate or coronatine treatments. The jas motif (82-103) lacks the canonical degron LPIARR that strongly interacts with COI1 in the presence of JA-Ile in other TIFY/JAZ proteins. Contains 1 EAR motif required for the interaction with TPL. Phosphorylated at multiple serine residues.
