NCIt definition : A fusion protein encoded by the SPECC1/PDGFRB fusion gene. This protein is comprised
of almost the entire cytospin-B protein fused to the C-terminal transmembrane and
cytoplasmic domains of the beta-type platelet-derived growth factor receptor protein,
including the protein kinase domain.;
NCIt note : The SPECC1/PDGFRB fusion protein is a constitutively dimerized and activated tyrosine
kinase.;
