Nipsnap1 (4-nitrophenyl phosphatase domain and non-neuronal SNAP-25 like protein homolog 1) is a novel mitochondrial protein that was shown to interact with the intracellular domain of the Alzheimer's Disease amyloid precursor protein (APP). Genetic knock-down mouse model of the Nipsnap1 protein (NipKD) expression resulted in a reduction of brain size and an increase in neuronal death measured by immunohistochemical analyses (TUNEL, activated Caspase 3 and FluoroJade-C staining). In addition, there was a robust increase in activated Caspase 3 and FluoroJade-C staining in kainic acid treated NipKD brains compared to the WT brains. This work provides the first evidence that Nipsnap1 plays an important role in the brain and that disruption of Nipsnap1 expression causes neurodegeneration. Because Nipsnap1 directly interacts with APP, this work may provide new insights into the pathogenesis of Alzheimer's Disease and possibly new therapeutic strategies.
