Runt-related transcription factor-binding protein 2
SAS2 and TIP60 protein 3
TIP60 protein 3
Zinc finger protein 220
Histone acetyltransferase that acetylates lysine residues in histone H3 and histone H4 (in vitro). Component of the MOZ/MORF complex which has a histone H3 acetyltransferase activity. May act as a transcriptional coactivator for RUNX1 and RUNX2.
Note=Chromosomal aberrations involving MYST3 may be a cause of acute myeloid leukemias. Translocation t(8;16)(p11;p13) with CREBBP; translocation t(8;22)(p11;q13) with EP300. MYST3-CREBBP may induce leukemia by inhibiting RUNX1-mediated transcription. Inversion inv(8)(p11;q13) generates the MYST3-NCOA2 oncogene, which consists of the N-terminus part of MYST3/MOZ and the C-terminus part of NCOA2/TIF2. MYST3-NCOA2 binds to CREBBP and disrupts its function in transcription activation. Note=A chromosomal aberration involving MYST3 is a cause of therapy-related myelodysplastic syndrome. Translocation t(2;8)(p23;p11.2) with ASXL2 generates a MYST3-ASXL2 fusion protein.
