MEMO1 (mediator of ErbB2-driven cell motility 1) regulates HER2-dependent cell migration. Increased MEMO1 expression is associated with cancer aggressiveness. Here, we found that MEMO1 is also involved in breast carcinogenesis via regulating insulin-like growth factor-I receptor-dependent signaling events. We showed that MEMO1 binds to insulin receptor substrate 1, activates the downstream PI3K/Akt signaling pathway, leads to upregulation of Snail1 and thereby triggers the epithelial-mesenchymal transition (EMT) program. In addition, MEMO1 overexpression is accompanied by growth factor-independent proliferation, anchorage-independent growth in soft agar, and enhanced metastatic potential. Together, these findings suggest that MEMO1 acts as an oncogene and is a potential therapeutic target for cancer treatment.

Although conserved throughout animal kingdoms, the protein encoded by the gene Mediator of ERBB2 Driven Cell Motility 1 or MEMO1, has only recently come into focus. True to its namesake, MEMO1 first emerged from a proteomic screen of molecules bound to the ERBB2 receptor and was found to be necessary for efficient cell migration upon receptor activation. While initially placed within the context of breast cancer metastasis-a pathological state that has provided tremendous insight into MEMO1's cellular roles-MEMO1's function has since expanded to encompass additional cancer cell types, developmental processes during embryogenesis and homeostatic regulation of adult organ systems. Owing to MEMO1's deep conservation, a variety of model organisms have been amenable to uncovering biological facets of this multipurpose protein; facets ranging from the cellular (e.g., receptor signaling, cytoskeletal regulation, redox flux) to the organismal (e.g., mineralization and mineral homeostasis, neuro/gliogenesis, vasculogenesis) level. Although these facets emerge at the intersection of numerous biological and human disease processes, how and if they are interconnected remains to be resolved. Here, we review our current understanding of this 'enigmatic' molecule, its role in development and disease and open questions emerging from these previous studies.
