The Trk proto-oncogene encodes a 140 kDa, membrane-spanning protein tyrosine kinase that is expressed only in neural tissues. Nerve growth factor (NGF) stimulates phosphorylation of Trk A in neural cell lines and in embryonic dorsal root ganglia. Affinity cross-linking and equilibrium binding experiments with 125I-labeled NGF indicate that Trk A binds NGF specifically in cultured cells with a dissociation constant of 10(-9) molar. The identification of Trk A as an NGF receptor indicates that this protein participates in the primary signal transduction mechanism of NGF (1). Trk A was found to be expressed in the nervous system and phosphorylated in response to NGF (Nerve Growth Factor). Somatic rearrangement(s) of the TRKA gene (also designated NTRK1) are responsible for formation of some oncogenes (2). Trk A is expressed in neural and nonneuronal tissues. Like RET, Trk A is often activated by rearrangements that involve one of at least five other genes in papillary thyroid carcinoma (PTC) (3).

FAQs for TrkA Antibody (NBP1-47436). (Showing 1 - 1 of 1 FAQ).

  1. I am searching (with difficulty) for an antibody against Trka which can be used in flow cytometry. Since I am planning to use it for bead sorting of live cells it needs to be for a part of the receptor which is on the outside of the cell. Please can you let me know if you can help me with this.
    • NBP1-47436, NB100-98815 and NB100-65266 all bind to the extracellular domain of Trka, however, none of them are guaranteed for use in flow cytometry. Our only flow cytometry guaranteed antibodies bind to the intracellular domain. This does not mean one of these antibodies won't work for flow, we just can not guarantee it. If you would be interested in testing this novel application on one of our Trka antibodies, please take a look at our Innovators Reward Program.
