4EBP1

4EBP1 is a protein that plays a key role in controlling how cells grow and produce proteins. It acts as a brake on a process called translation, where cells make new proteins. When signals promote cell growth, 4EBP1 is usually modified in a way that releases this brake, allowing protein production to proceed. Conversely, when growth signals are low, 4EBP1 stays active and suppresses protein synthesis. This regulation is important for maintaining healthy cell function and growth, and its malfunction is linked to diseases like cancer.
