BACKGROUND ABL tyrosine kinases control actin remodeling in development and in response to environmental stimuli. These changes affect cell adhesion, cell migration, and cell-cell contact. Little is known, however, about upstream mechanisms regulating ABL protein activation. RESULTS We report that the RAS effector RIN1 is an activator of ABL tyrosine(More)
The Ras effector Rin1 is induced concomitant with synaptogenesis in forebrain neurons, where it inhibits fear conditioning and amygdala LTP. In epithelial cells, lower levels of Rin1 orchestrate receptor endocytosis. A 945 bp Rin1 promoter fragment was active in hippocampal neurons and directed accurate tissue-specific and temporal expression in transgenic(More)
The amygdala is known to have a crucial role in both the acquisition and extinction of conditioned fear, but the physiological changes and biochemical mechanisms underlying these forms of learning are only partly understood. The Ras effector Rin1 activates Abl tyrosine kinases and Rab5 GTPases and is highly expressed in mature neurons of the telencephalon(More)
