Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Probable transcription factor acting as a positive regulator in the ethylene response pathway. Is required for ethylene responsiveness in adult plant tissues. Binds a primary ethylene response element present in the ETHYLENE-RESPONSE-FACTOR1 promoter with consequence to activate the transcription of this gene. Ref.1 Ref.4
Subunit structure	Acts as homodimer to bind the primary ethylene response element.
Subcellular location	Nucleus.
Miscellaneous	Loss-of-function mutations (ein3-1 and ein3-2) in the gene lead to the suppression of ethylene-mediated effects including gene expression, the triple response, cell growth inhibition, and accelerated senescence.
Sequence similarities	Belongs to the EIN3 family.
