Their superantigenic activity can be attributed to their ability to bind to both major histocompatibility complex (MHC) class II molecules and T cell receptors by forming a trimolecu

Despite this high stability, structural flexibility may be a very important parameter to control their functions such as recognition of certain T-cell receptor (TCR) V.-chains.

Directed Evolution of T-Cell Receptors for Binding Superantigens,ext of a major histocompatibility complex (pMHC) provides for the specificity of a cell-mediated immune response. However, this normal antigen recognition event can be circumvented by bacterial and viral proteins called superantigens (SAgs) (.). These unprocessed antigens bind to and thereby crossli
