Transcription

alternate splicing in 3

Proteins

Description

the proteins 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 name
inv(16)(p13q22), t(16;16)(p13;q22), and del(16)(q22) in acute non lymphoblastic leukaemia (AML) or myelodysplastic syndromes (MDS) --> CBFB - MYH11
Disease
nearly pathognomonic of M4eo-AML: with eosinophilia; frequent CNS involvement
Prognosis
high CR rate; better prognosis than most other AML
Cytogenetics
the 3 chromosome anomalies are variants of each other
Hybrid gene
5 CBFb - 3 MYH11
Fusion protein
the N-trem and most of CBFb is fused to the MYH11 C-term with its multimerization domain
