Gangliotetraose

Gangliotetraose (Gg4) is a tetrasccharide, exhibits major components including GM1 and its sialylated derivatives. GM1 facilitates efflux of nuclear Ca2+ and reduces the level of nuclear Ca2+ that characterizes the differentiated neuron. GM1 affects neuronal plasticity and repair mechanisms, as well as neurotrophin release in the brain[1][2].
