Trk stands for Topomyosin-Related Kinase. TrkA ligand - nerve growth factor activates the receptor by stabilizing homodimer formation which initiates transautophosphorylation. See also Neurotrophin. Relevance TrkA has a role in the pathogenesis of psoriasis and its inhibitors are studied in the development of novel therapeutics for the disease. TrkA inhibition may be a novel therapeutic approach to Alzheimer disease and a new method to treat intractable pain. Structural highlights Structure of Nerve Growth Factor Complexed with the Extracellular Domain of TrkA. An Arg residue, conserved in all neutrophins, forms the most important binding determinant between TrkA and its ligand - nerve growth factor - which forms the active homodimer of the receptor, . All interactions between TrkA chain A and NGF.
