MEMO1 (Mediator of ErbB2-Driven Cell Motility 1) is a conserved eukaryotic protein implicated in diverse cellular processes, including growth signaling, cytoskeletal dynamics, and redox regulation. Initially identified as a downstream effector of ErbB2 (HER2) receptor tyrosine kinase signaling, it plays a critical role in cancer cell migration, invasion, and metastasis. Structurally, MEMO1 contains conserved domains that facilitate interactions with key signaling components like the ErbB2-EGFR complex, IκB kinase (IKK), and the iron-binding protein PCBP1. Its involvement in reactive oxygen species (ROS) homeostasis and iron metabolism further links it to cellular stress responses and pathological conditions such as neurodegenerative diseases and malignancies.
Recombinant MEMO1 protein is typically produced using expression systems (e.g., *E. coli* or mammalian cells) with affinity tags (His-tag, GST) for purification. This engineered protein serves as a vital tool for studying MEMO1's molecular mechanisms, including its role in growth factor signaling (e.g., EGFR/ErbB2 pathways), microtubule stabilization, and iron-dependent enzyme regulation. Researchers utilize it in biochemical assays (pull-downs, kinase activity tests), structural studies (X-ray crystallography), and drug discovery targeting cancers with MEMO1 overexpression, particularly HER2-positive breast cancer. Its conserved functional motifs also make it relevant for evolutionary studies across species. Current research focuses on clarifying MEMO1’s dual roles in pro-survival signaling and oxidative stress modulation, highlighting its potential as a therapeutic target or biomarker in precision oncology.
