In cell-free binding studies, GFRalpha1-Ig displayed strong preferential binding to GDNF, though in the presence of soluble RET, weak binding to ART could also be detected. However, using GFRalpha1-transfected NB41A3 cells, ART showed no detectable competition against the binding of (125)I-labeled GDNF. Moreover, ART failed to induce phosphorylation of extracellular signal-related kinase (ERK) and Akt in these cells and was >10(4)-fold less potent than GDNF in stimulating RET phosphorylation. When rat primary dorsal root ganglion (DRG) neurons were used, only the survival promoting activity of GDNF and not that of ART was blocked by an anti-GFRalpha1 antibody. These results indicate that although ART can interact weakly with soluble GFRalpha1 constructs under certain circumstances in vitro, in cell-based functional assays GFRalpha1 is at least 10 000-fold selective for GDNF over ART. The extremely high selectivity of GFRalpha1 for GDNF over ART and the low reactivity of ART for this receptor suggest that GFRalpha1 is not likely to be a functional coreceptor for ART in vivo.","is_dataset_classified":null,"base_score":3.6888794541139363,"endowment":3.6888794541139363,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"15709767","pmcid":null,"openalex_id":"https://openalex.org/W2020719892","authors":[],"funders":[],"total_grants":0,"fwci":1.3097,"citation_percentile":0.76456136,"influential_citations":0,"citation_trend":[{"year":2012,"count":1},{"year":2013,"count":3},{"year":2014,"count":3},{"year":2015,"count":2},{"year":2016,"count":4},{"year":2018,"count":2},{"year":2020,"count":2},{"year":2023,"count":1},{"year":2024,"count":2}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://pubs.acs.org/doi/pdf/10.1021/bi049247p","host_type":"publisher"},{"url":"https://doi.org/10.1021/bi049247p","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/15709767","host_type":"repository"}],"fields_of_study":["Nerve injury and regeneration","Neurogenesis and neuroplasticity mechanisms","Axon Guidance and Neuronal Signaling"],"mesh_terms":["Animals","Cell Line","Cell Membrane","Cell Survival","Ganglia, Spinal","Humans","Nerve Growth Factors","Nerve Tissue Proteins","Neurons, Afferent","Phosphorylation","Protein Binding","Proto-Oncogene Proteins","Solutions","Transfection","Signal Transduction","Rats, Sprague-Dawley","Surface Plasmon Resonance","Receptor Protein-Tyrosine Kinases","Cell Line, Tumor","Proto-Oncogene Proteins c-ret","Glial Cell Line-Derived Neurotrophic Factor Receptors","Glial Cell Line-Derived Neurotrophic Factor","Mice","Rats"],"keywords":["Glial cell line-derived neurotrophic factor","GDNF family of ligands","Neurturin","Neurotrophic factors","Chemistry","Cell biology","Receptor","Neuroscience","Biology","Biochemistry"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-04T14:12:43.196454Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
