富含亮氨酸的重复蛋白激酶2(LRRK2)的突变是遗传性帕金森病(PD)的常见原因。该蛋白很大且复杂,但致病突变聚集在包含GTP酶和激动域的区域。在体外,LRRK2可以在一对二聚体中自动磷酸化,尽管这一反应的意义尚不清楚。在这里,我们定位了LRRK2中的自动磷酸化位点,并在GTPase结构域中发现了几个潜在的磷酸化位点。使用质谱仪,我们发现Thr1343是磷酸化的,并且使用LRRK2的激酶死亡版本,表明这是一个自动磷酸化的位点。然而,我们也发现在GTPase结构域和蛋白质的其他区域存在额外位点的证据,表明在LRRK2中可能存在多个自动磷酸化位点。这些数据表明,LRRK2的激酶和GTPase活性可能表现出复杂的自我调节相互依赖关系。
Mutations in Leucine-rich repeat kinase 2 (LRRK2) are a common cause of inherited Parkinson’s disease (PD). The protein is large and complex, but pathogenic mutations cluster in a region containing GTPase and kinase domains. LRRK2 can autophosphorylate in vitro within a dimer pair, although the significance of this reaction is unclear. Here, we mapped the sites of autophosphorylation within LRRK2 and found several potential phosphorylation sites within the GTPase domain. Using mass spectrometry, we found that Thr1343 is phosphorylated and, using kinase dead versions of LRRK2, show that this is an autophosphorylation site. However, we also find evidence for additional sites in the GTPase domain and in other regions of the protein suggesting that there may be multiple autophosphorylation sites within LRRK2. These data suggest that the kinase and GTPase activities of LRRK2 may exhibit complex autoregulatory interdependence.
