The fusion protein contains the first 741 residues of KANK1 fused to the last 692 residues of PDGFRB (Medves et al., 2010). This includes several coiled-coil domains of KANK1 and the fifth immunoglobulin-like domain, the transmembrane domain and the kinase domain of PDGFRB. The deletion of the immunoglobulin-like domain does not affect the oncogenic activity of the fusion (Medves et al., 2010). By contrast, deletion of the coiled-coil domains prevents cell transformation and signaling via STAT5 and MAP kinases (Medves et al., 2011). Our data suggest that KANK1-PDGFRB adopts a trimeric and multimeric conformation (Medves et al., 2011).
