Focal adhesion kinase (FAK), encoded by the *PTK2* gene, is a non-receptor tyrosine kinase critical for regulating cell adhesion, migration, survival, and proliferation. It localizes to focal adhesions, dynamic structures linking the extracellular matrix (ECM) to the cytoskeleton. FAK activation occurs via integrin-mediated signaling or growth factor receptors, triggering autophosphorylation at Tyr397. This recruits downstream effectors (e.g., Src, PI3K) to regulate cellular processes. Dysregulated FAK signaling is implicated in cancer metastasis, fibrosis, and cardiovascular diseases, making it a therapeutic target.
Recombinant FAK proteins are engineered to study its structure, interactions, and signaling mechanisms. Typically produced in *E. coli* or mammalian expression systems, these proteins retain functional domains: an N-terminal FERM domain, central kinase domain, and C-terminal focal adhesion-targeting (FAT) domain. Tagged versions (e.g., His, GST) facilitate purification and detection. Applications include *in vitro* kinase assays, binding studies, inhibitor screening, and antibody production. Mutant variants (e.g., kinase-dead or phosphorylation-site mutants) help dissect signaling pathways. Recombinant FAK also aids drug discovery, particularly in developing ATP-competitive inhibitors or allosteric modulators. Its use in structural biology (e.g., crystallography, cryo-EM) has advanced understanding of FAK regulation and inhibitor binding modes. Despite challenges in maintaining post-translational modifications, recombinant FAK remains vital for mechanistic research and therapeutic development.
