CREB is a protein molecule that plays a significant role in the functioning of the brain. It is responsible for regulating important processes in the brain such as long-term memory, mood regulation, and learning. There are many synonyms for the word "CREB," such as cyclic AMP response element binding protein, phosphorylated CREB, CRE-binding protein, and CRE modulator protein. These terms are often used interchangeably to describe the same protein, and are commonly encountered in scientific literature discussing brain function and regulation. Understanding the different names for CREB can aid in grasping the multifaceted roles of this crucial protein.
