Probable transcription regulator (By similarity). Promotes histone acetylation during ethylene signaling in an EIN2-dependent manner, thus regulating positively ethylene-responsive genes (By similarity). Interacts with the Agrobacterium tumefaciens virulence protein F (VirF) in the nucleus (PubMed:26571494). Binds to EIN2 C-terminal region in the presence of ethylene (PubMed:27694846). Reduced ethylene sensitivity.
