CREB5 encodes the human gene, CAMP responsive element binding protein 5. It may also be known as: Cyclic AMP-responsive element-binding protein 5; CREB-5; cAMP-responsive element-binding protein 5; CRE-BPa; cAMP response element binding protein CRE-Bpa. The encoded protein has an amino acid length of 508 and a mass of 56.9 kDa. Other isoforms may exist. CREB5 is a member of the BZIP family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog, Chicken.
