Human GP145-TrkB/GP95-TrkB (TrkB) Protein

Background

Neurotrophic receptor tyrosine kinase 2 (NTRK2), often referred to as TrkB, interacts specifically with brain-derived neurotrophic factor (BDNF) and neurotrophin-4/5 (NT-4/5). This receptor is central to processes like neuroplasticity, synaptic strength regulation, and long-term potentiation—mechanisms foundational for cognitive functions such as learning and memory. In addition to its role in brain health, NTRK2 is involved in mood regulation, and aberrations in its signaling pathways are associated with neuropsychiatric disorders, including depression, anxiety, and schizophrenia, emphasizing its role in mental health research and therapeutic interventions.
