TrkA, B, and C Receptors
TrkA is a receptor tyrosine kinase (meaning it mediates its actions by causing the addition of phosphate molecules on certain tyrosines in the cell, activating cellular signaling).
There are other related Trk receptors (TrkB and TrkC), and there are other neurotrophic factors structurally related to NGF (BDNF, NT-3, and NT-4)
- TrkA mediates the effects of NGF
- TrkB binds and is activated by BDNF, NT-4, and NT-3
- TrkC binds and is activated only by NT-3

Famous quotes containing the word receptors:
“Our talk of external things, our very notion of things, is just a conceptual apparatus that helps us to foresee and control the triggerings of our sensory receptors in the light of previous triggering of our sensory receptors.”
—Willard Van Orman Quine (b. 1908)
