Vil1 (Villin-1) is a calcium-regulated actin-binding protein predominantly expressed in epithelial cells of the gastrointestinal tract, renal tubules, and sensory hair cells. It belongs to the gelsolin/villin superfamily, characterized by conserved gelsolin-like domains that enable actin filament severing, capping, and bundling. Vil1 plays a critical role in maintaining cell morphology, microvilli structure, and epithelial barrier function by modulating actin cytoskeleton dynamics. Its expression is tightly regulated during development and tissue-specific differentiation, making it a marker for absorptive enterocytes in the small intestine.
Recombinant Vil1 protein is engineered using expression systems (e.g., E. coli, mammalian cells) to produce purified, functional Vil1 for research and therapeutic applications. Studies leverage recombinant Vil1 to investigate its role in cell migration, polarization, and wound healing, as well as its involvement in pathological conditions such as inflammatory bowel disease (IBD) and cancer. In colorectal cancer, Vil1 overexpression is linked to tumor progression and metastasis, highlighting its potential as a diagnostic or prognostic biomarker.
The recombinant protein also serves as an antigen for antibody development, enabling targeted studies of Vil1's interactions with signaling molecules (e.g., Rho GTPases) or its calcium-dependent actin remodeling mechanisms. Additionally, it aids in structural analyses to resolve domain-specific functions, such as the N-terminal core’s actin-binding activity versus the C-terminal headpiece’s bundling properties. By providing a controlled, scalable source of Vil1. recombinant technology advances both basic research and translational efforts in epithelial biology and disease.
