Target intelligence / Profile preview

Neurotrophic Tyrosine Receptor Kinase 3 (NTRK3)

Target
NTRK3
Molecular classification
Receptor tyrosine kinase, Receptor
01

Overview

NTRK3 encodes the TrkC protein, a receptor tyrosine kinase that binds neurotrophin-3 (NT-3). Upon ligand binding, TrkC activates downstream signaling pathways involved in neuronal differentiation, survival, and synapse development. NTRK3 gene fusions are oncogenic drivers in various cancers and are actionable biomarkers for targeted therapy with TRK inhibitors.
