Dysbindin function
WebPrevious studies have indicated that dysbindin-1 functions in the regulation of synaptic activity. Recently, dysbindin-1 has also been documented to be involved in neuronal development. In this study, we identified necdin as a binding partner of dysbindin-1 using a yeast two-hybrid screen. Dysbindin-1 recruits necdin to the cytoplasm, thereby ... WebNov 17, 2009 · Dysbindin has been implicated in the pathogenesis of schizophrenia, but little is known about how dysbindin affects neuronal function in the circuitry underlying psychosis and related behaviors. Using a dysbindin knockout line (dys(-/-)) derived from the natural dysbindin mutant Sandy mice, we have explored the role of dysbindin in …

WebJun 23, 2009 · Specifically, although our results do not negate the proposed mechanisms that involve dysbindin function in the adult brain, 22, 24, 25, 27 a role for BLOC-1 in the regulation of neurite outgrowth ... WebThus, it has been proposed that dysbindin may regulate trafficking or tethering of receptors and signal transduction proteins at the PSD in the glutamate synapse. 99 Dysbindin is also concentrated in the presynaptic glutamatergic terminals, where it interacts with SNAP and synapsin 1 and modulates vesicular release of glutamate. 113,114 ...
WebNov 17, 2009 · We have studied the role of dysbindin in dopamine signaling and neuronal functions, using a dysbindin mutant line. There are three major findings: 1) Mutation of dysbindin resulted in an … WebNov 11, 2009 · Dysbindin functions downstream or independently of the presynaptic Ca V 2.1 calcium channel in the mechanisms of synaptic homeostasis. Emerging lines of evidence suggest that glutamate hypofunction could be related to the etiology of schizophrenia (20–24). Likewise, reduced levels of dysbindin expression were associated with …
WebJan 1, 2005 · This hypothesis is supported circumstantially by the demonstration that knockdown of endogenous dysbindin protein results in reduction of glutamate release. 12 One attractive interpretation of these data is that polymorphisms in DTNBP1 result in reduced expression of dysbindin, that this results in disturbances of BLOC-1 function, … WebAt the functional level, dysbindin plays a role in NMDAR function because sdy hippocampal neurons exhibit an upregulation of NR2A subunits and enhanced long-term potentiation (Tang et al., 2009). Dysbindin is a component of the multisubunit BLOC-1 ...
WebNov 24, 2009 · Dysbindin altered the calcium dependence of vesicle release and was essential in the presynaptic neuron for both the induction and expression of synaptic homeostasis. D. K. Dickman, G. W. Davis, The schizophrenia susceptibility gene dysbindin controls synaptic homeostasis.
WebJun 20, 2012 · Thus, although Dysbindin and Snapin both participate in homeostatic plasticity and may function together in this process, Dysbindin has a separable activity that alters the apparent cooperativity of presynaptic release. We next determined the extent to which Snapin functions with Dysbindin to promote synaptic transmission. canine thymoma in cranial mediastinumWebMay 27, 2011 · Dysbindin (also known as dysbindin-1 or dystrobrevin-binding protein 1) was identified 10 years ago as a ubiquitously expressed protein of unknown function.
