What is NTRK1?

NTRK1, also known by many aliases—MTC, TRK, TRKA, High affinity nerve growth factor receptor, TRK1-transforming tyrosine kinase protein, Tropomyosin-related kinase A, Tyrosine kinase receptor, Tyrosine kinase receptor A, gp140trk—is a receptor tyrosine kinase that plays a critical role in neuronal growth and survival.

When its ligand, nerve growth factor (NGF), binds to NTRK1, the receptor undergoes dimerization and autophosphorylation, triggering downstream signaling pathways including MAPK/ERK, PI3K/AKT, and PLCγ. These pathways influence cell survival, differentiation, synaptic plasticity, and growth of nerve fibers.

Roles of NTRK1 in Health

1. Neurodevelopment: Essential for the maturation of sensory neurons and the development of the peripheral nervous system.
2. Maintenance of Neuron Function: Supports neuronal survival, synaptic maintenance, and plasticity in the mature nervous system.
3. Pain Sensation: Because NTRK1 is a receptor for NGF, it is involved in pain modulation—making it a target of interest in pain disorders.
4. Disorders from Mutation: Mutations in NTRK1 can cause conditions such as Congenital Insensitivity to Pain with Anhidrosis (CIPA), affecting pain perception and sweat production.

NTRK1 and Cancer

One of the most exciting areas where NTRK1 has clinical importance is in the field of oncology:

1. NTRK1 Gene Fusions: When NTRK1 becomes fused with other genes, the resulting fusion proteins can drive tumor growth by constitutively activating the receptor.
2. Therapeutic Targeting: TRK inhibitors such as larotrectinib and entrectinib have been developed to target NTRK fusion-positive tumors and have shown remarkable results.
3. Cancers Involved: These fusions have been discovered in a variety of tumors, including thyroid cancer, lung cancer, pediatric sarcomas, and gliomas.

Importance in Neuroscience and Beyond

Beyond cancer, NTRK1 is central in research on:

1. Neurodegenerative diseases: Alzheimer’s, Parkinson’s, and others where NGF/NTRK1 signaling might be disrupted.
2. Regeneration after injury: Stimulating NTRK1 signaling may promote neuronal repair.
3. Pain management: Because of its role in NGF signaling, blocking or modulating NTRK1 is under investigation for new analgesic approaches.
