CREB (cAMP response element-binding protein) is a cellular transcription factor. This protein binds the cAMP response element (CRE), a sequence present in many viral and cellular promoters. CREB is closely related in structure and function to CREM (cAMP response element modulator) and ATF-1 (activating transcription factor-1) proteins. CREB proteins are expressed in many animals.
