NTRK3 as a dependence receptor

When neuronal cells are deprived of the NTRK3 (TRKC) ligand NTF3 (NT-3), NTRK3 functions as a dependence receptor, promoting apoptosis. The pro-apoptotic activity of NTRK3 is implicated in proper nervous system development, by dictating the number of surviving sensory neurons (Tauszig-Delamasure et al. 2007). In the absence of its ligand, NTRK3 undergoes caspase-dependent cleavage (Tauszig-Delamasure et al. 2007), resulting in release of the NTRK3 killer fragment (KF). The NTRK3 KF, in complex with NELFB (COBRA1), inserts into the mitochondrial membrane, promoting cytochrome c release and apoptosome-mediated apoptosis (Ichim et al. 2013).
