a transcription factor that is a member of the leucine zipper family. Isolated and characterized as the cAMP-response element binding protein 2 (CREB-2). Involved in cisplatin resistance. Other members of the family include AP-1 transcription factors, cAMP-response element binding proteins (CREBs) and CREB-like proteins. Two alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
Molecular Function: DNA binding; leucine zipper domain binding; protein binding; sequence-specific DNA binding; transcription factor activity
