PTK2 and lung cancer: [24] clarified that DGKα phosphorylated the proto‐oncogene tyrosine‐protein kinase Src (SRC) protein and focal adhesion kinase 1 (FAK) protein to form and activate the DGKα/SRC/FAK complex, thereby initiating the downstream WNT/β‐catenin and VEGF signaling pathways, promoting EMT and angiogenesis, and resulting in the metastasis of non‐small cell lung cancer.
