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 dendritric cells has been suggested to play a negative modulating role in certain bacterial infections such as listeria. Here, CD81 blocks Rac activation, leading to reduced postinfection survival. Mouse CD81 shares 92%‑94% aa sequence identity with human and rat CD81.
