细胞与细胞外基质的相互作用触发整合素细胞表面受体开始调节肌动蛋白细胞骨架组织的信号级联。参与这些级联反应的蛋白之一是粘着斑激酶该基因编码的蛋白是一种GTPase激活蛋白，它与粘着斑激酶结合并介导GTP结合蛋白RHOA和CDC42的活性。该基因缺陷是青少年粒单核细胞白血病（JMML）的病因之一已发现该基因编码不同亚型的多个转录变体。[由RefSeq提供，2017年3月]
Interaction of a cell with the extracellular matrix triggers integrin cell surface receptors to begin signaling cascades that regulate the organization of the actin-cytoskeleton. One of the proteins involved in these cascades is focal adhesion kinase. The protein encoded by this gene is a GTPase activating protein that binds to focal adhesion kinase and mediates the activity of the GTP binding proteins RhoA and Cdc42. Defects in this gene are a cause of juvenile myelomonocytic leukemia (JMML). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2017]
