CC   -!- FUNCTION: Involved in ABA and stress responses and acts as a positive
CC       component of glucose signal transduction. Functions as transcriptional
CC       activator in the ABA-inducible expression of rd29B. Binds specifically
CC       to the ABA-responsive element (ABRE) of the rd29B gene promoter.
