FAK (Focal Adhesion Kinase)

Focal Adhesion Kinase (FAK) is a protein inside cells that helps them stick to their surroundings and communicate signals that regulate growth, movement, and survival. Located at sites where cells attach to the surrounding environment, FAK acts as a sensor and relay station, helping cells respond to changes and coordinate actions like migration or healing. It plays a crucial role in normal processes such as tissue repair and immune response, and its malfunction can contribute to diseases like cancer by enabling abnormal cell movement and growth.
