CD69 (Cluster of Differentiation 69) is a human transmembrane calcium-dependent lectin protein. CD69 functions as a signal-transmitting receptor in lymphocytes natural killer cells and platelets. CD69 expression is induced upon activation of T-cell lymphocytes. [1] Na ion binding site of CD69 C-type lectin-like domain dimer complex.[2]
