Background: CD81

CD81, also known as TAPA-1 and Tspan28, is a widely expressed protein in the Tetraspanin family. CD81 is a multifunctional protein that interacts with a variety of other molecules, including Tetraspanins, and is important for organization of the plasma membrane into microdomains. CD81 facilitates B cell and T cell activation and is an integrin-binding adhesion molecule. CD81 expression on lymphocytes is altered during infection by hepatitis C virus or HIV-1 and contributes to the pathogenicity of those viruses. Mouse CD81 shares 92%‑94% aa sequence identity with human and rat CD81.
