S6K1 (S6 Kinase 1)

S6K1 (S6 Kinase 1) is an enzyme that plays a key role in cell growth and protein production. It is activated by signals related to nutrients and growth factors, especially through a pathway called mTOR. Once active, S6K1 helps cells produce proteins necessary for growth, development, and metabolism. It also influences cell size and proliferation. Proper regulation of S6K1 is vital—too much activity can contribute to diseases like cancer, while insufficient activity can impair normal cell function. In summary, S6K1 acts as a molecular switch that promotes cell growth by enhancing protein synthesis.
