Composed of immunoglobulin G1 heavy chains and kappa light chains, it serves several functions.
Composed of immunoglobulin G1 heavy chains and kappa light chains, it serves several functions. It acts as the binding site for class II histocompatibility molecules and it interacts with the protein Lck to deliver co-stimulatory signals from crosslinking. However, it is probably most recognizable as the binding site for the gp120 protein, which allows a certain virus to overtake its cell. FTP, identify this glycoprotein receptor site on T cells that serves as the binding site for HIV.
