The CREB (Cyclic AMP-response-element-binding-protein 1) gene encodes a transcription factor that is a member of the leucine zipper family of DNA binding proteins.
This protein binds as a homodimer to the cAMP-responsive element (CRE element TGANNTCA), an octameric palindrome.
Phosphorylation by cAMPdependent protein kinase (PKA) at serine-119 is required for interaction with DNA and phosphorylation at serine-133 allows CREB to interact with CBP (CREB binding protein) leading to interaction with RNA polymerase II.
Alternate splicing of this gene results in two transcript variants encoding different isoforms.
