Schematic of the CEV14-PDGFRβ fusion protein. The nucleotide and deduced amino acids sequences near the breakpoint of the CEV14-PDGFRβ fusion are shown at the bottom of the figure. The breakpoint is indicated by an arrow. CEV14 has a leucine zipper motif 5′ of the breakpoint. TRIP indicates the predictive thyroid hormone receptor interacting domain. The PDGFRβ split tyrosine kinase domain is shown. tm indicates transmembrane domain.
