Ras

Ras is a family of proteins found inside cells that act as molecular switches, controlling how cells grow, divide, and communicate. When activated by signals, Ras switches on pathways that lead to cell proliferation and survival. Proper regulation of Ras is crucial, as mutations can cause it to stay permanently active, leading to uncontrolled cell growth and cancer. Ras functions as a key component in signal transduction, translating external cues into cellular responses, and plays an essential role in maintaining normal cell behavior and function.
