Repressor of jasmonate (JA) responses. Forms a ternary complex with RSS3 and BHLH94 to negatively regulate JA-responsive genes. Acts as positive regulator of tolerance to salt stress. Involved in salt tolerance by modulating potassium homeostasis through JA signaling and regulation of the expression of potassium ion transporter genes. Acts as a transcriptional regulator targeted by the SCF(COI1) E3 ubiquitin ligase complexes in the JA signaling pathway, and interacts with BHLH062 that may directly regulate the ion transporter genes. Acts as positive regulator of tolerance to dehydration stress. Acts as negative regulator of tolerance to cold stress by interacting with MYB30.

Western blot analysis of TIFY11A on rice tissue lysates. Proteins were transferred to a PVDF membrane and blocked with 5% NFDM/TBST for 1 hour at room temperature. The primary antibody (HA500265, 1/1,000) was used in 5% NFDM/TBST at room temperature for 2 hours. Goat Anti-Rabbit IgG - HRP Secondary Antibody (HA1001) at 1:200,000 dilution was used for 1 hour at room temperature.
