CREB (cAMP Response Element-Binding Protein)

CREB (cAMP Response Element-Binding Protein) is a protein in cells that helps regulate gene activity in response to signals like hormones or other stimuli. When activated, CREB binds to specific regions of DNA called cAMP response elements, turning genes on or off. This process influences important functions such as learning, memory, cell growth, and survival. CREB acts as a key communication link between external signals and the cell’s genetic response, enabling cells to adapt to changing conditions and play essential roles in brain function and development.
