**Background of NTRK2 Recombinant Protein**
The **NTRK2** (Neurotrophic Tyrosine Receptor Kinase 2) gene encodes a member of the tropomyosin receptor kinase (Trk) family, which plays a critical role in neuronal survival, differentiation, and synaptic plasticity. The protein product, TrkB, is a transmembrane receptor activated by binding to brain-derived neurotrophic factor (BDNF) and neurotrophin-4 (NT-4). Structurally, TrkB includes an extracellular ligand-binding domain, a transmembrane region, and an intracellular tyrosine kinase domain.
Recombinant NTRK2 protein is engineered *in vitro* to mimic the native receptor’s functional properties, often produced in heterologous systems like mammalian cells or bacteria. This recombinant form enables researchers to study TrkB signaling mechanisms, ligand-receptor interactions, and downstream pathways (e.g., MAPK/ERK, PI3K/Akt) in controlled environments. Its applications span neuroscience research, drug discovery, and disease modeling.
Dysregulation of NTRK2 is implicated in neurological disorders (e.g., Alzheimer’s, depression) and cancers. In oncology, *NTRK2* gene fusions—where the kinase domain is aberrantly linked to other genes—drive oncogenic signaling, making it a target for precision therapies like TRK inhibitors (e.g., larotrectinib). Recombinant NTRK2 aids in screening such inhibitors and understanding resistance mechanisms.
Additionally, recombinant variants may include tags (e.g., Fc fusion, His-tag) for purification or detection, facilitating structural studies and assay development. By enabling precise manipulation of TrkB signaling, recombinant NTRK2 remains vital for advancing both basic research and therapeutic innovation.
