Cytoplasmic polyadenylation element-binding protein (CPEB)

Cytoplasmic polyadenylation element-binding protein (CPEB) is a regulator found in cells that controls how specific messenger RNAs (mRNAs) are modified after they are made. Its main role is to influence the length of a tail called the poly(A) tail at the end of mRNAs, which affects how efficiently these messages are used to produce proteins. CPEB's activity is crucial in processes like cell growth, learning and memory, and development. By managing the timing and amount of protein production from certain mRNAs, CPEB helps cells respond appropriately to various signals and maintain proper function.
