Trka Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
Mermaid diagram (expand to render)
NTRK1 (Neurotrophic Receptor Tyrosine Kinase 1), also known as TRKA, is the high-affinity receptor for Nerve Growth Factor (NGF) and plays essential roles in the development and maintenance of the nervous system <sup>[1]</sup>. TRKA is a receptor tyrosine kinase that initiates pro-survival, differentiation, and proliferation signaling in NGF-responsive [neurons](/entities/neurons) including sympathetic neurons, sensory neurons, and cholinergic neurons of the basal forebrain. Mutations in NTRK1 cause congenital insensitivity to pain with anhidrosis (CIPA), and altered TRKA signaling is implicated in Alzheimer's disease, Parkinson's disease, and neuropathic pain <sup>[2]</sup>.
