Compositions and methods are presented that allow for an enhanced immune response against a GPI-anchored tumor associated antigen by modification of the protein portion of the TAA to include a transmembrane domain and a trafficking signal that directs the modified protein to the endosomal or lysosomal compartment. Most preferably, the modified protein will no longer have a GPI anchor or GPI attachment sequence.
