Fusion results in the joining of the N-terminal domain of ETV6 to the tyrosine kinase-containing C-terminal of PDGFRB. This leads to oligomerization at the pointed domain, constituently active phosphorylation, and activation of STAT proteins<ref>Chen J, Williams IR, Kutok JL, Duclos N, Anastasiadou E, Masters SC, et al.
