**Background of TLN1 Recombinant Protein**
Talin-1 (TLN1) is a cytoskeletal protein encoded by the *TLN1* gene, playing a pivotal role in cell adhesion, migration, and mechanotransduction. It acts as a critical linker between integrins—transmembrane receptors mediating cell-extracellular matrix interactions—and the actin cytoskeleton. Structurally, TLN1 contains an N-terminal FERM domain (F3 subdomain) that binds integrin cytoplasmic tails and a C-terminal flexible rod domain that associates with actin filaments. This dual binding capability enables TLN1 to regulate integrin activation, clustering, and downstream signaling, thereby influencing cell adhesion strength, spreading, and motility.
Dysregulation of TLN1 is implicated in pathological processes, including cancer metastasis, thrombosis, and immune disorders. For instance, reduced TLN1 expression correlates with impaired platelet aggregation, while its overexpression in tumors may enhance invasive potential. These associations highlight TLN1 as a potential therapeutic target or biomarker.
Recombinant TLN1 protein is produced using expression systems (e.g., *E. coli*, mammalian cells) to study its biochemical and biophysical properties. Purified TLN1 retains functional domains, enabling *in vitro* investigations such as integrin binding assays, actin polymerization studies, or mechanosensitive signaling experiments. Researchers also utilize TLN1 variants (e.g., truncated forms, mutations) to dissect domain-specific functions or mimic disease-related alterations.
Applications span basic research (e.g., elucidating focal adhesion dynamics) to drug discovery (e.g., screening small molecules targeting integrin-TLN1 interactions). Its recombinant form is essential for structural studies (e.g., cryo-EM, X-ray crystallography) and developing engineered cell models to explore mechanobiology. Overall, TLN1 recombinant protein serves as a vital tool for unraveling cellular mechanics and designing precision therapies.
