FAK(focal adhesion kinase) discovered by Schaller is a major substance which can be activated by src-ingeneration protein-tyrosine kinase and it is a non-receptorprotein-tyrosion kinase.

• 黏着斑激酶(focal adhesion kinase，FAK)是Schaller等发现的能被scr内源性蛋白酪氨酸激酶激活的主要底物，属于非受体蛋白酪氨酸激酶，具有调节细胞发育、生长、存活和凋亡，调节细胞与ECM(细胞外基质)黏附的功能。
