ELMO1 (engulfment and cell motility 1) is a scaffolding protein essential for cytoskeletal rearrangement and cell migration. It functions as a guanine nucleotide exchange factor (GEF) activator by binding DOCK proteins (DOCK1-5) to promote Rac1 GTPase activation 1. This DOCK/ELMO complex mediates actin cytoskeletal reorganization required for phagocytosis of apoptotic cells and bacterial clearance, fundamental to innate immunity 2. ELMO1 expression is epigenetically regulated through multiple transcript variants, with brain-specific expression patterns suggesting tissue-dependent functions 3. Clinically, ELMO1 polymorphisms (rs741301, rs1345365, rs10951509) show significant associations with diabetic kidney disease (DKD) susceptibility across multiple populations, particularly in the Middle East 456. ELMO1 is also implicated in inflammatory diseases; TNF-α-mediated upregulation of ELMO1 in ankylosing spondylitis mesenchymal stem cells enhances pathological cell migration, and ELMO1 inhibition provides therapeutic benefits 7. In cancer, ELMO1 overexpression in melanoma and other malignancies correlates with enhanced cell survival, migration, and metastatic potential through Rac1-ERK/AKT signaling 82. These findings establish ELMO1 as a potential diagnostic biomarker and therapeutic target across metabolic, inflammatory, and malignant diseases.
