NCIt definition : A fusion protein encoded by the MLL/GPHN fusion gene. This protein is comprised of
the N-terminal half of the histone-lysine N-methyltransferase MLL protein, including
the AT hook DNA binding domain and the DNA methyltransferase domain, fused with the
C-terminus of the gephyrin protein including the presumed tubulin-binding site and
a domain homologous to the E. coli molybdenum cofactor biosynthesis protein.;
