Summary: Enables DNA-binding transcription factor activity, RNA polymerase II-specific and protein heterodimerization activity. Involved in several processes, including defense response to bacterium; egg chorion assembly; and imaginal disc fusion, thorax closure. Located in cytosol and nucleus. Part of transcription factor AP-1 complex. Is expressed in several structures, including amnioserosa primordium; dorsal ectoderm; epithelial cell; epithelium; and larval internal muscle motor neurons. Human ortholog(s) of this gene implicated in head and neck squamous cell carcinoma; melanoma; and pulmonary tuberculosis. Orthologous to several human genes including JUNB (JunB proto-oncogene, AP-1 transcription factor subunit) and JUND (JunD proto-oncogene, AP-1 transcription factor subunit).
