FAK (Focal Adhesion Kinase) is a non-receptor tyrosine kinase that plays a crucial role in cellular processes such as adhesion, migration, proliferation, and survival. It is primarily localized at focal adhesions, where it interacts with integrins and other signaling molecules.
FAK promotes cell proliferation by activating signaling pathways such as the PI3K/Akt and MAPK/ERK pathways. These pathways are often upregulated in cancer cells, leading to uncontrolled growth.
