GD3

GD3 ganglioside is abundantly expressed on all melanomas but not expressed on most normal tissues. Gangliosides are complex glycolipid constituents of cell membranes. They are involved in many biological functions including cell-cell recognition, cell-matrix attachment, cell growth and cell differentiation. They are synthesized in the Golgi apparatus of the cell as a consequence of multienzyme pathways leading to different substructures.
