Inhibitory Member of the Apoptosis-stimulating Proteins of the p53 Family (iASPP) Interacts with Protein Phosphatase 1 via a Noncanonical Binding Motif

Abstract excerpt

Although kinase mutations have been identified in various human diseases, much less is known about protein phosphatases. Here, we show that all apoptosis-stimulating proteins of p53 (ASPP) family members can bind protein phosphatase 1 (PP1) via two distinct interacting motifs. ASPP2 interacts with PP1 through an RVXF PP1 binding motif, whereas the inhibitory member of the ASPP family (iASPP) interacts with PP1...
