ELMO2 (Engulfment and Cell Motility Protein 2) is a conserved cytoplasmic adaptor protein that plays critical roles in regulating cytoskeletal dynamics, cell migration, and intracellular signaling. It belongs to the ELMO protein family, which interacts with Dock180 (Dedicator of Cytokinesis 1) to form the ELMO-Dock180 complex. This complex functions as a bipartite guanine nucleotide exchange factor (GEF) for Rac1. a small GTPase of the Rho family, promoting the activation of Rac1-dependent pathways. Rac1 activation drives processes such as actin reorganization, membrane protrusion, and cell motility, making ELMO2 essential for physiological and pathological processes, including embryonic development, immune cell trafficking, and cancer metastasis.
The recombinant ELMO2 protein is engineered for research applications to study its molecular interactions, structural features, and functional mechanisms. Produced through heterologous expression systems (e.g., bacteria, mammalian cells), recombinant ELMO2 retains its ability to bind Dock180 and other partners, enabling in vitro assays to dissect signaling cascades. Its modular structure, featuring PH (Pleckstrin Homology) and SH3 (Src Homology 3) domains, facilitates protein-protein and protein-membrane interactions. Researchers utilize recombinant ELMO2 to investigate its role in diseases; for example, dysregulated ELMO2 expression is linked to cancer progression, inflammatory disorders, and neurological conditions. Additionally, it serves as a tool to screen potential therapeutic compounds targeting Rac1-mediated pathways. The development of recombinant ELMO2 has significantly advanced our understanding of cell motility regulation and its implications in health and disease.
