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.

Specificity

Recognizes p125FAK; does not cross react with Pyk-2.

Immunogen

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

Application

Anti-FAK Antibody, clone 4.47 is an antibody against FAK for use in IC, IH, IP & WB.
