Upon activation by NTF3 (NT-3), the receptor tyrosine kinase NTRK3 (TRKC) triggers RAS signaling through adaptor proteins SHC1 and GRB2 (Marsh and Palfrey 1996, Gunn-Moore et al. 1997, Yuen and Mobley 1999). ERK activation downstream of NTRK3 may increase cell motility through WAVE. The mechanism is not known (Gromnitza et al. 2018).
