Notes

Phosphotyrosine TrkB ELISA Kit (ab279957) is a very rapid, convenient and sensitive assay kit that can monitor the activation or function of important biological pathways in human cell lysates. By determining phosphorylated TrkB protein in your experimental model system, you can verify pathway activation in your cell lysates. You can simultaneously measure numerous different cell lysates without spending excess time and effort in performing a Western Blotting analysis.

This Sandwich ELISA kit is an in vitro enzyme-linked immunosorbent assay for the measurement of human phospho-TrkB. An anti-TrkB antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and phosphorylated and unphosphorylated TrkB present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-phosphotyrosine antibody is used to detect only tyrosine-phosphorylated protein. After washing away unbound antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of phospho-TrkB bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Activity summary

TrkB also known as Neurotrophic Tyrosine Kinase Receptor Type 2 (NTRK2) is a cell surface receptor with a mass of approximately 145 kDa. It binds brain-derived neurotrophic factor (BDNF) and is widely expressed in the central nervous system particularly in areas like the hippocampus cortex and cerebellum. TrkB belongs to the family of receptor tyrosine kinases functioning by catalyzing the transfer of a phosphate group from ATP to specific tyrosine residues on substrate proteins in the receptor triggering downstream signaling cascades.

Biological function summary

TrkB plays essential roles in neuronal survival differentiation and synaptic plasticity. It acts as an important mediator for the effects of neurotrophins primarily BDNF on neurons. While TrkB itself is not part of a multi-protein complex it interacts closely with several adaptor proteins post-activation to propagate survival and proliferation signals within the neuron. These biochemical interactions greatly influence neurodevelopment and cognitive functions.

Pathways

TrkB is a pivotal player in both the MAPK/ERK and PI3K/AKT pathways. Upon BDNF binding TrkB undergoes autophosphorylation triggering these pathways which are critically involved in cell survival and growth. Other proteins such as SHC1 and PLCγ interact with TrkB in these pathways extending the range of cellular responses to neurotrophin signaling facilitating processes like neuronal plasticity and memory formation.

Associated diseases and disorders

TrkB has significant implications in neurological conditions like Alzheimer's disease and depression. In Alzheimer's disease alterations in TrkB signaling can result in impaired cognitive functions and neuronal loss where it interacts with proteins like amyloid-beta contributing to disease progression. In depression dysfunctional BDNF-TrkB signaling impacts mood regulation and resilience linking TrkB with alterations in serotonin receptor signaling emphasizing its role in mood disorders.
