Application

TrkB/Fc Chimera human can be used in synaptoneurosome preparation and western blot analysis. Intracerebroventricular administeration of TrkB/Fc chimera human blocks TrkB ligand signaling and was used to study the role of BDNF in ATN response augmentation.

Biochem/physiol Actions

Member of the Trk family tyrosine kinase receptors. Binds specifically to mediate neurotrophins BDNF and NT-4/5.
TrkB/Fc Chimera human consist of extracellular domain of human TrkB1 fused to histidine-tagged Fc region of human IgG1 by using a polypeptide linker. TrkB belongs to tyrosine kinase receptors family and facilitates the hippocampal development as well as regulating the synaptic plasticity that underlies long-term potentiation and learning. Brain derived neurotrophic factor (BDNF) and Neurotrophin 4 or 5 are preferred ligands for TrkB. Nevertheless it can also bind to NTF3/neurotrophin-3 that is less efficient in activating the receptor but regulates neuron survival through NTRK2.

Other Notes

Extracellular domain of human TrkB fused to the C-terminal histidine-tagged Fc region of human IgG1.

Physical form

Lyophilized from 0.2 μm filtered solution in phosphate buffered saline.

Reconstitution

Reconstitute to 100 μg/mL in phosphate buffered saline.

Analysis Note

Inhibits BDNF-induced proliferation of TrkB transfected cells, BaF-TrkB-BD.

Brain-derived neurotrophic factor (BDNF) plays an important role in learning and memory in multiple brain areas. In the present study, we investigated the roles of BDNF in aversive memories associated with conditioned drug withdrawal in acute morphine-dependent rats. Conditioned place

The hippocampus projects to the anterior thalamic nuclei both directly and indirectly via the mammillary bodies, but little is known about the electrophysiological properties of these convergent pathways. Here we demonstrate, for the first time, the presence of long-term plasticity

Lithium has been used to treat major depressive disorder, yet the neural circuit mechanisms underlying this therapeutic effect remain unknown. Here, we demonstrated that the ventral tegmental area (VTA) dopamine (DA) neurons that project to the medial prefrontal cortex (mPFC)

Learning-induced trophic activity is thought to be critical for maintaining health of the aging brain. We report here that learning, acting through an unexpected pathway, activates synaptic receptors for one of the brain's primary trophic factors. Unsupervised learning, but not

We have isolated two novel variants involving the extracellular domain of TrkB from developing sensory neurons. These variants are generated by alternative splicing and lack two or all three of the leucine-rich motifs. Each of these variants is expressed as
