摘要: Neural stem cells continuously generate new neurons in the ventricular-subventricular zone (V-SVZ) of postnatal and adult mammalian brain. New born rodent V-SVZ migrate toward olfactory bulb (OB), where they differentiate into interneurons. To reveal novel intracellular molecular mechanisms that control neuronal migration, we performed a global proteomic search for proteins interacting with Girdin, an essential protein migration. Using GST pull-down LC-MS/MS shotgun analysis, identified cytoskeletal proteins, cytoskeleton-binding signal-transduction as possible participants Our results suggest Girdin Girdin-interacting migration by regulating actin and/or microtubule dynamics.
