肝细胞生长因子(HGF)诱导细胞分散前紧密连接解体的机制在很大程度上是未知的。在这里,我们表明,HGF刺激快速损失的TJ组装蛋白Par 6从TJ的ERK依赖的方式。发现HGF激活Erk介导Par 6与载GTP的Cdc 42的相互作用。Cdc 42 GTP酶激活蛋白cdGAP显示在基线与Pkc激酶相互作用并阻止Par 6-Cdc 42缔合。Erk通过在苏氨酸776处磷酸化cdGAP,可以抑制差距活性,从而增加Par 6-Cdc 42缔合和TJ分解。我们的研究结果揭示了一种新的途径,通过Erk-cdGAP调节HGF信号传导到Par蛋白,导致TJ分解和细胞分散。
The mechanism by which Hepatocyte Growth Factor (HGF) induces tight junction disassembly prior to cell scattering is largely unknown. Here, we show that HGF-stimulates rapid loss of the TJ assembly protein Par6 from the TJ in an Erk-dependent manner. Erk activation by HGF is found to mediate the interaction of Par6 with GTP-loaded Cdc42. The Cdc42 GTPase activating protein cdGAP is shown to interact with Pkcζ at baseline and prevent Par6-Cdc42 association. Erk, by phosphorylating cdGAP at threonine776, can inhibit the GAP activity, thereby increasing Par6-Cdc42 association and TJ disassembly. Our findings reveal a novel pathway for regulating HGF signaling to the Par proteins through Erk-cdGAP, resulting in TJ disassembly and cell scattering.
