Arhgef1 Deletion Disrupts Early Cortical Neurogenesis via PAK1 Overactivation and Causes Motor Dysfunction in Adulthood

Advanced Science, EarlyView.
ARHGEF1 plays a pivotal role in both embryonic cortical neurogenesis and adult motor function. During early development, it governs genesis of deep‐layer cortical neurons by negatively regulating RAC1/CDC42‐PAK1‐Cofilin signaling. In adulthood, ARHGEF1 is important for the maintenance of neuronal morphology and activity in the motor cortex, ensuring ...
