Trk receptors are a family of three receptor tyrosine kinases (TrkA, TrkB, and TrkC), each of which can be activated by one or more of the four neurotrophins nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and neurotrophins 3 and 4 (NT3 and NT4).
The TRK receptor family is made up of the transmembrane proteins TrkA, TrkB, and TrkC. These receptor tyrosine kinases are expressed in human neuronal tissue and are crucial for the physiology of nervous system development and function. Neurotrophins (NTs) activate these receptor tyrosine kinases. For TrkA, BDGF, NT-4/5, and TrkB and TrkC, respectively, these latter substances are specific ligands known as NGF and NT-3.
When a ligand binds to a receptor, the receptors begin to oligomerize and certain tyrosine residues in the intracytoplasmic kinase domain become phosphorylated. As a result of this action, signal transduction pathways that promote proliferation, differentiation, and survival in both healthy and malignant neuronal cells are activated.
