FunctionCD81 is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. CD81 mediates signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This protein is a cell surface glycoprotein that is known to complex with integrins. CD81 appears to promote muscle cell fusion and support myotube maintenance. It is localized in the tumor-suppressor gene region, and thus it is a candidate for malignancies.

Flow Cytometry - Anti-TAPA1 antibody; Overlay histogram showing Jurkat cells stained with TA307303 (red line). The secondary antibody used was Alexa Fluor 488 goat anti-rabbit IgG (H&L) at 1:2000. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1ug/1x10^6 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. This antibody gave a positive signal in Jurkat cells under the same conditions.
