Rho样GTPase rac1诱导细胞迁移所需的细胞骨架重排。RAC活性通过一系列机制来调节,包括控制核苷酸交换和水解、调节亚细胞定位或调节蛋白质表达水平。在这里,我们确定了小泛素样修饰物(SUMO)E3连接酶,PIAS3,作为一种新的rac1相互作用因子,需要增加Rac活性和响应肝细胞生长因子(HGF)信号的最佳细胞迁移。我们发现,在HGF的作用下,rac1可以结合到SUMO-1上,并且PIAS3可以促进SUMO的作用。此外,我们确定了在rac1的多碱基区域内的非共识位点是相扑接合的主要位置。我们证明了PIAS3介导的rac1的SUMO化控制了它的GTP结合水平和它刺激片状脂血症、细胞迁移和侵袭的能力。这是第一次发现RAS超家族成员被SUMO化,为调节这些细胞行为的关键调节因子提供了新的见解。此外,我们的数据揭示了相扑在调节细胞迁移和侵袭中以前未被描述的作用。
The Rho-like GTPase Rac1 induces cytoskeletal rearrangements required for cell migration. Rac activity is regulated through a number of mechanisms, including control of nucleotide exchange and hydrolysis, regulation of subcellular localization, or modulation of protein expression levels. Here, we identify the Small Ubiquitin-like MOdifier (SUMO) E3-ligase, PIAS3, as a new Rac1 interactor required for increased Rac activity and optimal cell migration in response to Hepatocyte Growth Factor (HGF) signalling. We show that Rac1 can be conjugated to SUMO-1 in response to HGF and that SUMOylation is enhanced by PIAS3. Moreover, we identify non-consensus sites within the polybasic region of Rac1 as the main locations for SUMO conjugation. We demonstrate that PIAS3-mediated SUMOylation of Rac1 controls its GTP-bound levels and its ability to stimulate lamellipodia, cell migration and invasion. This is the first time that a Ras superfamily member is found to be SUMOylated, providing a new insight into the regulation of these critical mediators of cell behaviour. Moreover, our data reveal a previously undescribed role for SUMO in the regulation of cell migration and invasion.
