Vtn Gene Summary [Rat]
Enables collagen binding activity; heparin binding activity; and identical protein binding activity. Involved in liver regeneration and protein polymerization. Located in several cellular components, including Golgi lumen; basement membrane; and rough endoplasmic reticulum lumen. Used to study proteinuria. Biomarker of diabetic retinopathy. Human ortholog(s) of this gene implicated in Churg-Strauss syndrome; granulomatosis with polyangiitis; and thrombosis. Orthologous to human VTN (vitronectin).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Vtn often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
