a receptor tyrosine kinase of the Trk family. Receptor for brain-derived neurotrophic factor (BDNF), neurotrophin-3, -4 and -5 but not nerve growth factor (NGF). Involved in the development and maintenance of the nervous system. Three splice variant isoforms have been described. Note: This description may include information from UniProtKB.
