Psychiatry related information on Ntrk3

 

High impact information on Ntrk3

  • Actions of the truncated TrkB receptor did not involve unmasking of endogenous TrkC signaling [6].
  • To determine whether neurotrophins act on functionally distinct populations of adult sensory neurons, the distributions of mRNAs for TrkA and tyrosine kinase-containing isoforms of TrkB and TrkC were determined in rat DRG neurons projecting to different peripheral targets [7].
  • Stable and transient expression of TrkC receptors in PC12 cells indicates that the neurite outgrowth response elicited by NT-3 is dramatic in receptors lacking the novel kinase insert (gp150trkC) but absent in receptors containing the 14 amino acid insert in the kinase domain (gp150trkC14) [8].
  • Finally, forms of TrkC containing insertions within the kinase domain retain their ability to autophosphorylate in response to neurotrophin-3, but cannot mediate proliferation in fibroblasts or neuronal differentiation in PC12 cells [9].
  • Other forms of TrkC contain variable-sized amino acid insertions within the tyrosine kinase domain [9].

Anatomical context of Ntrk3

 

Associations of Ntrk3 with chemical compounds

  • No significant alterations to the expression of TrkC mRNA were found indicating that ethanol-exposure appears to act selectively on the BDNF communication system [19].
  • Prior reports demonstrated that cells of the oligodendroglial lineage are susceptible to excitotoxic necrosis mediated by alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid glutamate receptors (AMPA-GluR), and also showed that these cells express the high affinity neurotrophin receptors, TrkC and TrkA [20].
  • A Western blot of CG-4 and C6 probed with antibody to a TrkC revealed the presence of gp145-kDa protein band [1].
 

Enzymatic interactions of Ntrk3

  • However, we found the TrkC receptor constitutively phosphorylated even in the absence of added ligand suggesting an interaction of TrkC with endogenously produced NT-3 [11].
 

Regulatory relationships of Ntrk3

  • Here we have studied whether this difference can be attributed to the presence of alternative TrkC receptor variants on the granule neurons and which signaling pathway is specifically activated by BDNF but not by NT-3 in these neurons [11].
  • Our results demonstrate that NT-3 at any concentration sufficient to activate the TrkC receptor results in a transient phosphorylation of the receptor and of Akt due, in part, to downregulation of the Trk receptor [21].
