The function of Ensembl gene identifier ENSG00000130522 (JUND, JunD proto-oncogene, AP-1 transcription factor subunit) is as follows. 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). .
