Biological or Clinical Significance:

This protein is important in the development and survival of nerve cells (neurons), especially those that transmit pain, temperature, and touch sensations (sensory neurons). The NGFβ protein functions by attaching (binding) to its receptors, which initiates signaling pathways inside the cell. The NGFβ protein can bind to two different receptors, the NTRK1 receptor or the p75NTR receptor. Both receptors are found on the surface of sensory neurons and other types of neurons. The binding of the NGFβ protein to the NTRK1 receptor signals these neurons to grow and to mature and take on specialized functions (differentiate). This binding also blocks signals that initiate the process of self-destruction (apoptosis). Additionally, NGFβ signaling through NTRK1 plays a role in pain sensation. It is less clear what binding with the p75NTR receptor signals. Studies suggest that p75NTRsignaling can help sensory neurons grow and differentiate but can also trigger apoptosis.
