AMFR (Autocrine Motility Factor Receptor), also known as gp78. is a transmembrane glycoprotein that functions as an E3 ubiquitin ligase in the endoplasmic reticulum (ER)-associated degradation (ERAD) pathway. Initially identified for its role in cancer cell migration and metastasis, AMFR binds to autocrine motility factor (AMF/PGI), a cytokine secreted by tumor cells, to activate downstream signaling pathways that promote cytoskeletal reorganization, cell motility, and invasive behavior. This receptor gained broader attention due to its critical involvement in protein quality control within the ER. As a key component of the ERAD machinery, AMFR facilitates the ubiquitination and subsequent proteasomal degradation of misfolded or unassembled proteins, thereby maintaining cellular homeostasis and mitigating ER stress. Its RING finger domain mediates substrate recognition and ubiquitin transfer, while transmembrane regions anchor it to the ER membrane.
Research has linked AMFR dysregulation to various pathologies, including cancer progression, neurodegenerative diseases, and metabolic disorders. Overexpression of AMFR in tumors correlates with enhanced metastasis, poor prognosis, and chemoresistance, making it a potential therapeutic target. Conversely, impaired AMFR function is associated with the accumulation of toxic protein aggregates in conditions like Alzheimer’s and Parkinson’s diseases. Recombinant AMFR proteins are engineered to study its structural and functional dynamics, enabling investigations into substrate interactions, ubiquitination mechanisms, and regulatory post-translational modifications. These recombinant variants, often expressed in mammalian or insect cell systems, preserve native folding and enzymatic activity, serving as tools for drug screening, structural biology, and mechanistic studies. Ongoing research aims to develop AMFR-targeted therapies, such as small-molecule inhibitors or modulators, to address its role in disease pathogenesis.
