Focal adhesion kinase (FAK), a non‐receptor tyrosine kinase in the cytoplasm, couples with integrins and growth factor receptors to regulate cell adhesion, proliferation, migration, invasion, and metastasis.[1] FAK is overexpressed and aberrantly activated in many cancer types, including TNBC, and plays a critical role in tumor progression and metastasis.[2]. The gene discussed is PTK2; the disease is cancer.
