The ephrin/Eph system plays a central role in neuronal circuit formation; however, its downstream effectors are poorly understood. Here we show that alpha-chimerin Rac GTPase-activating protein mediates ephrinB3/EphA4 forward signaling. We discovered a spontaneous mouse mutation, miffy (mfy), which results in a rabbit-like hopping gait, impaired(More)
A major concern in neuroscience is how cognitive ability in adulthood is affected and regulated by developmental mechanisms. The molecular bases of cognitive development are not well understood. We provide evidence for the involvement of the α2 isoform of Rac-specific guanosine triphosphatase (GTPase)-activating protein (RacGAP) α-chimaerin (chimerin) in(More)
