Proteins

Description
2004 amino acids; 225 kDa; composed from N-term of: a NEMM domain (N-term region of ENOK, MOZ or MORF) including a H15 (linker H1 and H5 like) nuclear localization domain, 2 PHD (plant homeodomain, also known as LAP (leukemia associated protein)) Zn fingers (C4HC3), a C2HC Zn finger, essential part of the histone acyl transferase domain (HAT MOZ-SAS), an acidic (Glu-Asp) domain, localisation of breakpoints in the inv(8) and in the t(8;22) in 1118, and a Ser-(Pro-Glu)-Met rich domain, localisation of the t(8;16) breakpoint in 1547.
Localisation
Nucleus
Function
Lysine acetyltransferase activity (histone acyl transferase); MYST3 (MOZ) and MYST4 (MORF) possess both transcription activation and transcription repression domains; transcriptional regulators; interact with RUNX1 and RUNX2; Moz, the zebrafish ortholog of MYST3, was also found to regulate Hox expression; Moz behaves like a trithorax group factor.
Homology
with MYST4 (MORF) (monocytic leukemia zinc finger protein-related factor), a transcription regulator with positive and negative domains and activities.
Implicated in
Entity name
t(2;8)(p23;p11) in therapy related myelodysplastic syndrome --> KAT6A / ?
Disease
Only 1 case to date, a boy aged 6 years.
Entity name
Disease
Erythrophagocytosis; very rare: less than 10 cases; young age, and female sex.
Prognosis
likely to be poor
Hybrid gene
5 MYST3 - 3 NCOA2
Fusion protein
The fusion product retains the zinc fingers, the the histone acetyl transferase (HAT) domain of MYST3 and the HAT domains and CREBBP interacting domain of NCOA2.
Entity name
t(8;16)(p11;p13) in acute myelomonocytic or monocytic leukaemia (M4 or M5 AML) and therapy related AML (t-AML) --> KAT6A / CREBBP
Disease
Erythrophagocytosis; rare: less than 1% of AML; found in children and young adults of both sex.
Prognosis
poor
Hybrid gene
5 MYST3 - 3 CREBBP
Fusion protein
The fusion product retains the zinc fingers, the HAT domain of MYST3 and most of CREBBP, including the CREBBP interacting domain and the HAT domain; the fusion protein may repress RUNX1-dependant gene expression.
Entity name
Disease
Erythrophagocytosis; very rare: less than 5 cases.
Prognosis
likely to be poor
Oncogenesis
EP300 is very similar to CRBBP (see above), the breakpoints on these 2 genes are on homologous regions; the breakpoint on MYST3 is more proximal in the t(8;22).
