TWF1 (Twinfilin-1), a member of the ADF/cofilin protein family, is a conserved actin-binding protein critical for regulating cytoskeletal dynamics. It contains two actin-depolymerizing factor (ADF)-homology domains, enabling its interaction with both monomeric (G-actin) and filamentous actin (F-actin). TWF1 modulates actin polymerization by sequestering G-actin and capping filament barbed ends, thereby balancing actin assembly-disassembly cycles essential for cell motility, morphogenesis, and endocytosis. Its activity is tightly regulated by phosphorylation and interactions with signaling molecules like PIP2 and Rho GTPases.
Recombinant TWF1 proteins are engineered to study its structural and functional properties. Typically produced in *E. coli* or eukaryotic expression systems, these proteins retain biochemical activity while enabling controlled experimental conditions. Tags such as His-tag or GST are often fused to facilitate purification and detection. Recombinant TWF1 has been instrumental in elucidating its role in diseases; for example, dysregulated TWF1 expression correlates with cancer metastasis, immune disorders, and neurological defects. It also serves as a tool for drug screening targeting cytoskeleton-related pathologies.
Recent studies highlight TWF1's involvement in mechanotransduction and cellular stress responses, expanding its relevance beyond basic cytoskeletal regulation. The development of phosphorylation-mimetic mutants (e.g., Ser/Thr to Asp substitutions) has further advanced understanding of post-translational regulation. As actin dynamics gain attention in therapeutic strategies, recombinant TWF1 remains a key reagent for dissecting pathological mechanisms and developing precision interventions.
