Cell localization:Nucleus.function:Transcription factor that recognizes and binds toThe enhancer heptamer motif 5-TGA[CG]TCA-3.,PTM:Phosphorylation enhancesThe transcriptional activity. Phosphorylated by PRKDC.,similarity:Belongs toThe bZIP family.,similarity:Belongs toThe bZIP family. Jun subfamily.,similarity:Contains 1 bZIP domain.,subunit:Heterodimer with either FOS or BATF3. Interacts with HIVEP3 (By similarity). Interacts with SMAD3/SMAD4 heterodimers. Interacts with MYBBP1A, SPIB and TCF20. Interacts with COPS5, indirectly leading to its phosphorylation. Interacts with DSIPI, this interaction inhibitsThe binding of active AP1 to its target DNA.,
