<P> MHC class I molecules are one of two primary classes of major histocompatibility complex ( MHC ) molecules ( the other being MHC class II ) and are found on the cell surface of all nucleated cells in the bodies of jawed vertebrates . They also occur on platelets , but not on red blood cells . Their function is to display peptide fragments of non-self proteins from within the cell to cytotoxic T cells ; this will trigger an immediate response from the immune system against a particular non-self antigen displayed with the help of an MHC class I protein . Because MHC class I molecules present peptides derived from cytosolic proteins , the pathway of MHC class I presentation is often called cytosolic or endogenous pathway . </P>
