Trk receptors: mediators of neurotrophin action.
The four mammalian neurotrophins - NGF, BDNF, NT-3 and NT-4 - each bind and activate one or more of the Trk family of receptor tyrosine kinases. Through these receptors, neurotrophins activate many intracellular signaling pathways, including those controlled by Ras, the Cdc42/Rac/RhoG protein family, MAPK, PI3K and PLC-gamma, thereby affecting both development and function of the nervous system...
متن کاملActivation of Trk neurotrophin receptors in the absence of neurotrophins.
Neurotrophins regulate neuronal cell survival and synaptic plasticity through activation of Trk receptor tyrosine kinases. Binding of neurotrophins to Trk receptors results in receptor autophosphorylation and downstream phosphorylation cascades. Here, we describe an approach to use small molecule agonists to transactivate Trk neurotrophin receptors. Activation of TrkA receptors in PC12 cells an...
متن کاملAssociation of Trk neurotrophin receptors with components of the cytoplasmic dynein motor.
Nerve growth factor (NGF) initiates its trophic effects by long-range signaling through binding, internalization, and transport of a ligand-receptor complex from the axon terminal to the cell body. However, the mechanism by which retrograde transport of NGF takes place has not been elucidated. Here we describe an interaction between the Trk receptor tyrosine kinase and a 14 kDa light chain of c...
متن کاملNeurotrophin Trk receptors in the brain of a teleost fish, Nothobranchius furzeri.
Trk neurotrophin receptors are transmembrane tyrosine kinase proteins known as TrkA, TrkB, and TrkC. TrkA is the high affinity receptor for nerve growth factor, TrkB is the one for both brain-derived neurotrophic factor and neurotrophin-4, and TrkC is the preferred receptor for neurotrophin-3. In the adult mammalian brain, neurotrophins are important regulators of neuronal function and plastici...
متن کاملOntogenetic expression of trk neurotrophin receptors in the chick auditory system.
Neurotrophins and their cognate receptors are critical to normal nervous system development. Trk receptors are high-affinity receptors for nerve-growth factor (trkA), brain-derived neurotrophic factor and neurotrophin-4/5 (trkB), and neurotrophin-3 (trkC). We examine the expression of these three neurotrophin tyrosine kinase receptors in the chick auditory system throughout most of development....
