WebGM2 gangliosidosis is a rare genetic disorder that progressively destroys nerve cells in the brain and spinal cord. The most common form of the disease typically presents in infancy, but various other forms can present in childhood, adolescence, or even adulthood. GM2 gangliosidosis is sometimes called Tay-Sachs disease or HexA deficiency. Web4.1 Gangliosides as the key molecules for the assembly and function of lipid raft. Gangliosides in the cell membrane participate in various cell-surface interactions as ligands for biomolecules such as proteins and glycoconjugates. Cell-surface interactions can be divided into trans - and cis -interactions. Trans -interactions are interactions ...
