1 Our findings indicate that GM1-promoted survival can be mediated in part by the Trk NGF receptor as well as by TrkB, and potentially by tyrosine kinase receptors for additional neurotrophic growth factors. G(M1) Ganglioside neurotrophic receptor tyrosine kinase 1 Rattus norvegicus
2 Experiments employing K-252a, an inhibitor of Trk kinases, and PC12 cells overexpressing a dominant inhibitory form of Trk both indicate that a portion of the survival-promoting activity of GM1 is evoked by receptor dimerization and autophosphorylation. G(M1) Ganglioside neurotrophic receptor tyrosine kinase 1 Rattus norvegicus

G(M1) Ganglioside neurotrophic receptor tyrosine kinase 1 Rattus norvegicus
4 In consonance with this we find that GM1 stimulates Trk tyrosine autophosphorylation and Trk-associated protein kinase activity. G(M1) Ganglioside neurotrophic receptor tyrosine kinase 1 Rattus norvegicus
5 In consonance with this we find that GM1 stimulates Trk tyrosine autophosphorylation and Trk-associated protein kinase activity. G(M1) Ganglioside neurotrophic receptor tyrosine kinase 1 Rattus norvegicus
