MYH11 (myosin heavy chain) (incomplete)
| Identity |
| HGNC (Hugo) | MYH11 |
| Location | 16p13 |
| Location_base_pair | Starts at 15704493 and ends at 15858388 bp from pter ( according to hg18-Mar_2006) [Mapping] |
| Local_order | proximal (in 16p13.1) from CBP |
| DNA/RNA |

| Transcription | alternate splicing in 3¼ |
| Protein |
| Description | the protein¼s name is MYST; 214 KDa, 1857 amino acids known; N-term ATPase globular domain responsible for actin binding and mechanical movement, and a C-term long repeat of coil-coil domain to facilitate filament aggregates; forms hetero-hexameres |
| Expression | smooth muscle |
| Function | muscle contraction |
| Homology | member of the myosin II family |
| Implicated in |
| Entity | inv(16)(p13q22), t(16;16)(p13;q22), and del(16)(q22) in acute non lymphoblastic leukaemia (ANLL) or myelodysplastic syndromes (MDS) --> CBFb - MYH11 |
| Disease | nearly pathognomonic of M4eo-ANLL: with eosinophilia; frequent CNS involvement |
| Prognosis | high CR rate; better prognosis than most other ANLL |
| Cytogenetics | the 3 chromosome anomalies are variants of each other |
| Hybrid/Mutated Gene | 5¼ CBFb - 3¼ MYH11 |
| Abnormal Protein | the N-trem and most of CBFb is fused to the MYH11 C-term with its multimerization domain |
