CAMP responsive element binding protein 1 also known as CREB-1 is a protein that in humans is encoded by the CREB1 gene. This protein binds the cAMP response element a DNA nucleotide sequence present in many viral and cellular promoters. The binding of CREB1 stimulates transcription.This protein is a CREB 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 an octameric palindrome.
