Transcription factor required for yeast cell adherence to silicone substrate. Plays a role in resistance to weak organic acids such as acetate and sorbate. Binds in vitro to a nitric oxide-responsive element (NORE) but seems not to be involved in response to nitrosative stress. Homodimer. Expression is induced in biofilm. Leads to sensitivity to weak organic acids and decreases cell adherence to silicone substrate.
