Anti-FAK Antibody, clone 4.47

125 kDa

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.

GST fusion protein corresponding to residues 1-423 of human FAK (focal adhesion kinase); specific for p125FAK
