==Gene Overview==

==Gene Overview==

The MYH11 gene encodes a smooth muscle myosin belonging to the myosin heavy chain family. The gene product is a subunit of a hexameric protein that consists of two heavy chain subunits and two pairs of non-identical light chain subunits. It functions as a major contractile protein, converting chemical energy into mechanical energy through the hydrolysis of ATP.  The pericentric inversion of chromosome 16 [inv(16)(p13q22)] produces a chimeric transcript that encodes a protein consisting of the first 165 residues from the N terminus of core-binding factor beta in a fusion with the C-terminal portion of the smooth muscle myosin heavy chain.  

The ''MYH11'' gene encodes a smooth muscle myosin belonging to the myosin heavy chain family. The gene product is a subunit of a hexameric protein that consists of two heavy chain subunits and two pairs of non-identical light chain subunits. It functions as a major contractile protein, converting chemical energy into mechanical energy through the hydrolysis of ATP.  The pericentric inversion of chromosome 16 [inv(16)(p13q22)] produces a protein bearing the first 165 residues from the N terminus of core-binding factor beta (''CBFB'') and  the C-terminal portion of the smooth muscle myosin heavy chain (''MYH11'')<ref name=":0" />. The CBFβ–MYH11 fusion protein exerts a dominant negative function by increased binding to the transcription factor encoded by ''RUNX1'', thereby competing for free Runx1 protein and leading to lowered and altered transcription of myeloid genes<ref name=":0" />.

The CBFβ–MYH11 fusion gene encodes a protein that exerts a dominant negative function by  binding to the transcription factor encoded by ''RUNX1''.  The fusion protein encoded by CBFβ–MYH11 competes (10-fold increased binding affinity) with normal CBFbeta protein for free Runx1 protein, leading to lowered and altered transcription of myeloid genes normally controlled by the CBFbeta and Runx1 transcription factors<ref name=":0" />.
