Recombinant human WASL protein, also known as neural Wiskott-Aldrich syndrome protein (N-WASP), is a key regulator of actin cytoskeleton remodeling. Produced via genetic engineering in expression systems like *E. coli* or mammalian cells, recombinant WASL retains the functional domains necessary for orchestrating actin polymerization. It interacts with upstream signals such as Cdc42. phosphoinositides, and SH3 domain-containing proteins to activate the Arp2/3 complex, driving branched actin network formation. This process is critical for membrane protrusion, vesicle trafficking, and cell motility.
WASL is ubiquitously expressed but particularly vital in neural and immune cells. Dysregulation of its activity is implicated in pathologies, including cancer metastasis, immune deficiencies, and neurological disorders. Research leverages recombinant WASL to dissect molecular mechanisms of cytoskeletal dynamics, screen therapeutic compounds, or model disease-associated mutations. Its modular structure—featuring a C-terminal VCA domain (verprolin homology, cofilin homology, acidic region) and an autoinhibitory N-terminal domain—allows precise experimental manipulation to study activation/inhibition states.
As a tool, recombinant WASL enables high-resolution structural studies and real-time visualization of actin remodeling *in vitro*. Its applications span cell biology, drug discovery, and biomedical engineering, offering insights into cellular mechanics and potential therapeutic strategies targeting cytoskeleton-related diseases.
