We previously reported that the acute disruption of the Stk25 gene (Stk25 conditional knock-out; cKO) during mouse embryogenesis causes anomalous neuronal migration in the neocortex, but paradoxically the Stk25 cKO did not have a cortical phenotype, suggesting some forms of compensation exist. In this study, we report that MST3, another member of the GCKIII subgroup of the Ste20-like kinase family, compensates for loss of Stk25 and vice versa with sex independent manner. MST3 overexpression rescued neuronal migration deficit and abnormal axonogenesis in Stk25 cKO brains. Mechanistically, STK25 leads to Rac1 activation and reduced RhoA levels in the developing brain, both of which are required to fully restore neuronal migration in the Stk25 cKO brain. Abnormal migration phenotypes are also rescued by overexpression of Bacurd1and Cul3, which target RhoA for degradation, and activate Rac1. This study reveals that MST3 upregulation is capable of rescuing acute Stk25 deficiency and resolves details of signaling downstream STK25 required for corticogenesis both common to and distinct from MST3 signaling.SIGNIFICANCE STATEMENT Proper neuronal migration during cortical development is required for normal neuronal function. Here, we show that STK25 and MST3 kinases regulate neuronal migration and polarization in a mutually compensatory manner. Furthermore, STK25 balances Rac1 activity and RhoA level through forming complexes with α-PIX and β-PIX, GTPase regulatory enzymes, and Cullin3-Bacurd1/Kctd13, a pair of RhoA ubiquitination molecules in a kinase activity-independent manner. Our findings demonstrate the importance of overlapping and unique roles of STK25 and MST3 to regulate Rho GTPase activities in cortical development."xsd:string |
