It is intended to provide a protein interacting with c-Fos; an inhibitor using the same; a method of detecting the interaction with the use of a protein interacting with c-Fos; and a screening method. Using the in vitro virus (IVV) cotranslation method and the C-end labeling method, transcription regulatory factor complexes are overwhelmingly analyzed from a mouse brain cDNA library with the use of c-Fos as bait. Thus, proteins which have never been know so far or proteins which have never been known as forming a complex with c-Fos protein though having been known in public per se are analyzed.
