mTOR (mammalian Target of Rapamycin)

mTOR (mammalian Target of Rapamycin) is a crucial protein that acts as a cellular growth and energy sensor. It helps regulate cell growth, division, and survival by responding to nutrient availability, like amino acids and glucose, as well as signals from growth factors. Think of it as a biological master switch that coordinates how cells grow and reproduce based on their environment. Proper mTOR function is vital for healthy development and metabolism, but when it becomes overactive, it can contribute to diseases such as cancer and metabolic disorders.
