背景信息

EMR2 (EGF-like module-containing mucin-like hormone receptor 2), also known as ADGRE2. is a member of the adhesion G protein-coupled receptor (ADGR or GPCR) subfamily. It is characterized by a large extracellular N-terminal region containing multiple epidermal growth factor (EGF)-like domains and a mucin-like stalk, followed by a seven-transmembrane domain typical of GPCRs. EMR2 is predominantly expressed on immune cells, including neutrophils, monocytes, and macrophages, where it plays roles in cell adhesion, migration, and immune response regulation. Its structure suggests involvement in ligand binding via extracellular domains, though its endogenous ligands remain under investigation.

The interest in EMR2 stems from its association with inflammatory diseases and cancer. For instance, dysregulated EMR2 expression has been linked to rheumatoid arthritis, atherosclerosis, and tumor progression, potentially through modulating leukocyte activation or tumor microenvironment interactions. To study its functions, recombinant EMR2 proteins are engineered using expression systems like mammalian or insect cells to ensure proper post-translational modifications (e.g., glycosylation). These recombinant proteins retain key functional domains and are used in ligand-binding assays, structural studies, and therapeutic target validation.

Recent research focuses on developing EMR2-targeted therapies, such as monoclonal antibodies or small-molecule inhibitors, to modulate immune responses or disrupt cancer pathways. Additionally, recombinant EMR2 serves as a tool to decipher signaling mechanisms, including its proposed cleavage-dependent activation, where proteolytic processing of the extracellular domain triggers receptor signaling. Overall, EMR2’s unique structure and immune-related roles make it a compelling subject for both basic research and translational applications.
