MHC class I molecules has the ability to expresse on all the nucleated cells whereas class II MHC molecules are mainly expressed on the B cells and macrophages ( antigen presenting cells).

The processing of MHC class II molecule involves the following steps. The breakdown of proteins into fragments by the help of enzyme.

The complex is then transported to the plasma membrane.
