  • Function

    Receptor for brain-derived neurotrophic factor (BDNF), neurotrophin-3 and neurotrophin-4/5 but not nerve growth factor (NGF). Involved in the development and/or maintenance of the nervous system. This is a tyrosine-protein kinase receptor. Known substrates for the TRK receptors are SHC1, PI-3 kinase, and PLC-gamma-1.
  • Tissue specificity

    Isoform TrkB is widely expressed, mainly in the nervous tissue. In the CNS, expression is observed in the cerebral cortex, hippocampus, thalamus, choroid plexus, granular layer of the cerebellum, brain stem, and spinal cord. In the peripheral nervous system, it is expressed in many cranial ganglia, the ophtalmic nerve, the vestibular system, multiple facial structures, the submaxillary glands, and dorsal root ganglia. Isoform TrkB-T1 is expressed in multiple tissues, mainly in brain, pancreas, kidney and heart. Isoform TrkB-T-Shc is predominantly expressed in brain.

  • Anti-TrkB antibody (ab33655) at 1 µg/ml + Mouse brain membrane protein

    Predicted band size: 92 kDa

  • Immunohistochemical analysis of paraffin embedded mouse P29-RA lung section (10µm thick) labelling TrkB with ab33655 at 1:200 dilution. The secondary antibody was a peroxidase-labeled, polymer-conjugated goat anti-rabbit secondary antibody. Sections were stained with hematoxylin and eosin (H&E).

Thank you for contacting us. Having compared the anti-phospho antibodies provided by Santa Cruz to those of Abcam (ab52191 and ab51187) they appear to be suitable for the same application in targeting the phosphorylated tyrosine-705 and -515 of TrkB. There are three isoforms of human TrkB referenced by SwissProt (Q16620) of 92, 53 and 59 kDa. However, TrkB exists as variably glycosylated entities with the major forms having molecular weights of ~145 kDa, and the unglycosylated form of ~95kD kDa. The product in the western blot identified as a degradation product is therefore more likely the unglycosylated form of the protein. Thank you for bringing this to our attention we will be updating our datasheet accordingly. ab52191, ab51187 and ab51190 all target the C-terminal domain while ab33655 is directed against the extracellular domain. All of the antibodies should be able to identify both the glycosylated and unglycosylated forms of the protein. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
