Mint2/X11-like colocalizes with the Alzheimer's disease amyloid precursor protein and is associated with neuritic plaques in Alzheimer's disease.

Aberrant metabolism of the amyloid precursor protein ( APP) is believed to be at least part of the pathogenic process in Alzheimer's disease. The carboxy-terminus of APP has been shown to interact with the Mint/X11 family of phosphotyrosine binding (PTB) domain-bearing proteins. It is via their PTB domains that the Mints/X11s bind to APP. Here we report the cloning of full-length mouse Mint2 and demonstrate that in primary cortical neurons, Mint2 and APP share highly similar distributions. Mint2 also colocalizes with APP in transfected CHO cells. In Mint2/APP-cotransfected cells, Mint2 reorganizes the subcellular distribution of APP and also increases the steady-state levels of APP. Finally, we demonstrate that Mint2 is associated with the neuritic plaques found in Alzheimer's disease but not with neurofibrillary tangles. These results are consistent with a role for Mint2 in APP metabolism and trafficking, and suggest a possible role for the Mints/X11s in the pathogenesis of Alzheimer's disease.[1]
