A new pathway for the processing of β-amyloid precursor protein (APP) is described in which η-secretase activity, in part mediated by the MT5-MMP metalloproteinase, cleaves APP, and further processing by ADAM10 and BACE1 generates proteolytic fragments capable of inhibiting long-term potentiation in the hippocampus.
