Fos and pATF2 are competing monomers for the dimeric AP-1 transcription factor.
Auditory nerve stimulation counter-regulates Fos and pATF2 expression in hearing and deaf rats.
Increase of stimulation-dependent Fos expression is matched by decrease of pATF2 in AVCN and LSO.
Fos and pATF2 favor different plasticity-related transcription cascades.
