Activated wild-type NTRK3 (TRKC), as well as constitutively active ETV6-NTRK3 oncogene, a product of translocation between ETV6 and NTRK3 gene loci in congenital fibrosarcoma and cellular mesoblastic nephroma, are able to bind to adaptor protein IRS1 (Morrison et al. 2002, Lannon et al. 2004, Jin et al. 2008). Binding of IRS1 to NTRK3 is enhanced in the presence of SRC (Jin et al. 2008).
