TrkA: Proteins and Enzymes

TrkA, the product of the protooncogene trk, is a member of the neurotrophic tyrosine kinase receptor family that has three members. TrkA, TrkB and TrkC preferentially bind NGF, NT-4 and BDNF, and NT-3, respectively. All Trk family proteins share a conserved complex subdomain organization consisting of a signal peptide, two cysteine-rich domains, a cluster of three leucine-rich motifs, and two immunoglobulin-like domains in the extracellular region, as well as an intracellular region that ...
