Positive transcriptional factor that acts as a component of the stress responsive system. Recognizes and binds to the stress response element (STRE) which is involved in the response to various forms of stress (heat, oxidative, osmotic, etc.). Involved in the regulation of the CTT1, DDR2, HSP12 genes. the 9aaTAD motif (residues 237 to 245) is a transactivation domain present in a large number of yeast and animal transcription factors.
