NCIt definition : A fusion protein encoded by the CIC/DUX4 fusion gene. This protein is comprised of
the majority of the protein capicua homolog, including the DNA-binding high-mobility
group (HMG)-box and 15 of 16 putative MAPK phosphorylation sites, fused to the C-terminus
of double homeobox protein 4, which results in the loss of both of its DNA-binding
homeodomains.;
