NCIt definition : Soluble cytoplasmic non-receptor FAK (Focal Adhesion Kinase) Family Tyrosine Kinases
catalyze the phosphorylation of tyrosine residues in proteins with ATP or other nucleotides
as phosphate donors. FAK is found in intracellular signaling focal adhesion complexes
following engagement of the extracellular matrix by integrins. The C-terminal 'focal
adhesion targeting' (FAT) region is necessary and sufficient for localizing FAK to
focal adhesions.;
