General description

Focal adhesion kinase (FAK) is a cytoplasmic protein tyrosine kinase that has been implicated to play an important role in integrin-mediated signal transduction pathways. FAK becomes activated and tyrosine phosphorylated in integrin-mediated cell adhesion and is colocalized with integrins and other cytoskeletal proteins in focal contacts in a variety of adherent cells. Physical interactions of FAK with the integrin cytoplasmic domain as well as cytoskeletal proteins talin, paxillin, and/ or tensin have been proposed to play a key role in FAK activation by facilitating its oligomerization and transphosphorylation. FAK shows a rapid increase in tyrosine phosphorylation when stimulated by diverse signaling molecules, including those that regulate embryonic development, cell proliferation, migration and apoptosis, and efficient study methods are in high demand.
