**Background of CFL1 Recombinant Protein**
Cofilin-1 (CFL1) is a small actin-binding protein critical for regulating cytoskeletal dynamics by severing and depolymerizing actin filaments. This activity is essential for cellular processes such as migration, division, and intracellular trafficking. CFL1 functions in a pH-dependent manner and is regulated by phosphorylation; its inactive form (phosphorylated) is modulated by kinases like LIMK and phosphatases like SSH1. Dysregulation of CFL1 is linked to pathologies including cancer metastasis, neurodegenerative disorders, and immune dysfunction, underscoring its biomedical relevance.
Recombinant CFL1 protein is produced using genetic engineering techniques, typically expressed in *E. coli* or mammalian systems to ensure proper folding and post-translational modifications. Purification involves affinity chromatography, yielding high-purity protein for research applications. Recombinant CFL1 enables *in vitro* studies of actin dynamics, screening of kinase/phosphate inhibitors, and mechanistic exploration of diseases. For instance, it aids in modeling cancer cell invasion by mimicking cytoskeletal changes or studying synaptic plasticity alterations in Alzheimer’s disease.
In drug discovery, CFL1 serves as a target for modulating cytoskeletal behavior, with potential therapeutic implications for metastatic cancers or neuroinflammation. Its recombinant form also supports structural studies (e.g., X-ray crystallography) to map interaction sites with actin or regulatory molecules. Overall, CFL1 recombinant protein is a vital tool for dissecting cytoskeletal biology and developing targeted therapies.
