Reticulon-4 receptor (RTN4R)

Functions as receptor to the sialylated gangliosides GT1b and GM1 (PubMed:18411262). Can also bind heparin (By similarity).

Intracellular signaling cascades are triggered through the coreceptor NGFR (PubMed:12426574). Signaling mediates activation of Rho and downstream reorganization of the actin cytoskeleton (PubMed:16712417, PubMed:22325200).
