Regulated intramembrane proteolysis--lessons from amyloid precursor protein processing.

abstract：:This Editorial highlights a study by Xia and coworkers in the current issue of the Journal of Neurochemistry, in which the authors reveal a possible mechanistic link between DISC1 (disrupted-in-schizophrenia-1), a genetic risk factor for schizophrenia, and N-methyl-d-aspartate receptor (NMDAR) that is also linked with...
