Transcription factor binding AP-1 sites (PubMed:9989505). Heterodimerizes with proteins of the FOS family to form an AP-1 transcription factor complex, thereby enhancing their DNA binding activity to an AP-1 consensus sequence 3′-TGA[GC]TCA-5′ and enhancing their transcriptional activity (PubMed:28981703, PubMed:9989505).
