The function of Ensembl gene identifier ENSG00000171119 (NRTN, neurturin) is as follows. Growth factor that supports the survival of sympathetic neurons in culture (PubMed:8945474). May regulate the development and maintenance of the CNS (PubMed:8945474). Involved in the development of the neural crest (PubMed:15242795). Might control the size of non- neuronal cell population such as haemopoietic cells (PubMed:8945474). Acts by binding to its coreceptor, GFRA2, leading to autophosphorylation and activation of the RET receptor (PubMed:10829012, PubMed:29414779, PubMed:31535977). Heparan sulfate- binding is required for signaling (PubMed:29414779). {ECO:0000269|PubMed:10829012, ECO:0000269|PubMed:15242795, ECO:0000269|PubMed:29414779, ECO:0000269|PubMed:31535977, ECO:0000269|PubMed:8945474}.
