cAMP response element binding protein

The cAMP response element-binding protein (CREB) is a key molecular switch inside cells that helps regulate gene activity in response to various signals. When certain signals activate the cell, it increases levels of a molecule called cAMP, which triggers CREB to turn on specific genes. This process influences important functions like learning, memory, and cell survival. CREB works by attaching to specific DNA regions, acting as a messenger that translates external signals into changes in gene expression, thereby helping cells adapt and respond appropriately to their environment.
