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" />.

Acute Myeloid Leukemia (AML) with inv(16)(p13.1q22) or t(16;16)(p13.1;q22); CBFB-MYH11

Approximately 5-8% of AML cases have inv(16)(p13.1q22) or t(16;16)(p13.1;q22)[1][2]. Either rearrangement leads to a CBFB-MYH11 fusion gene and may be an early event in the development of Acute Myeloid Leukemia (AML)[3].

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 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)[3]. 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[3].

Common Alteration Types

inv(16)(p13.1q22) or t(16;16)(p13.1;q22); CBFB-MYH11

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[3].
