Description of CD81 Recombinant Protein

General Information about CD81 Recombinant Protein

CD81, also known as TAPA-1, belongs to the transmembrane superfamily 4, also known as the tetraspanin family. Members of this family mediate transduction events that play a role in the regulation of cell development, activation, growth and movement. CD81 is a widely expressed cell surface protein that participates in various amazing biological reactions. It involves the adhesion, morphology, activation, proliferation and differentiation of B cells, T cells and other cells. On B cells, CD81 is part of a complex with CD21, CD19 and Leul3. The combination of ag-specific recognition and CD21-mediated complementary recognition of the complex lowers the threshold for activation of the B cell B cell receptor.
