UniProtKB - P24898 (JUNB_RAT)
Transcription factor JunB
Junb
Functioni
Transcription factor involved in regulating gene activity following the primary growth factor response. Binds to the DNA sequence 5'-TGA[GC]TCA-3'. Heterodimerizes with proteins of the FOS family to form an AP-1 transcription complex, thereby enhancing its DNA binding activity to an AP-1 consensus sequence and its transcriptional activity (By similarity).

Binds DNA as a homodimer or as a heterodimer with another member of the Jun/Fos family.
Component of an AP-1 transcription factor complex (By similarity). As part of the AP-1 transcription factor complex, forms heterodimers with FOSB, thereby binding to the AP-1 consensus sequence and stimulating transcription (By similarity).
Interacts with NFE2 (via its WW domains).
