Inositol monophosphatase 1 (IMPA1) controls the activity of the primary cell proliferation signaling cascades activated through the inositol-dependent phosphorylation of Akt and PKCs. Furthermore, IMPA1 -mediated control of cell proliferation involves the recruitment of cytosolic IMPA1 on a plasma membrane by the receptor for advanced glycation endproducts (RAGE). Interaction between IMPA1 and RAGE redistributes inositols from the cytosolic pool to membrane microdomains and amplifies the synthesis of membrane-bound phosphatidylinositols (Ptdins) to trigger inositol-dependent cell proliferation. Thus, the peptide compositions described herein inhibit the formation of the complex between IMPA1 and RAGE (e.g., a pathogenic complex) to control over-proliferative cells.
