Purified recombinant fragment of human MYST1 expressed in E. Coli.

MYST1 (MYST histone acetyltransferase 1, MOF) belongs to the MYST family of histone acetyltransferases, which are employed in the cell to bring about transcriptional regulation. The MYST family includes MYST1, is named for the founding members MOZ, yeast YBF2 and SAS2, and TIP60. All members of this family contain a MYST region of about 240 amino acids with a canonical acetyl-CoA-binding site and a C2HC-type zinc finger motif. Most MYST proteins also have a chromodomain involved in protein- protein interactions and targeting transcriptional regulators to chromatin. Although MOF is expressed in both males and females, it associates with the X chromosome only in males. MOF contains a zinc-finger domain that is used to contact the globular part of the nucleosome and histone H4. The carboxy terminal domain of human MOF also has histone acetyltransferase activity directed against histones H3 and H2A, a characteristic shared with other MYST family histone

Research Backgrounds


Histone acetyltransferase which may be involved in transcriptional activation. May influence the function of ATM. As part of the MSL complex it is involved in acetylation of nucleosomal histone H4 producing specifically H4K16ac. As part of the NSL complex it may be involved in acetylation of nucleosomal histone H4 on several lysine residues. That activity is less specific than the one of the MSL complex. Can also acetylate TP53/p53 at 'Lys-120'.


Autoacetylation at Lys-274 is required for binding histone H4 with high affinity and for proper function.

Application: IHC    Species: human,mouse,rat    Sample: kidney

Figure 2. Mof was mainly expressed in pancreatic α -cells. IHC showed the cell location of Mof in islet was similar to glucagon, not insulin in human (A), rat (B) and mice (C) pancreas

Application: WB    Species: mouse    Sample: α-tc1-6

( E) Western blotting showed Mof protein expression s in 3, 10 and 25 mmol/L glucose in MIN6 were unchanged. ( F) Western blotting showed Mof protein expression was decreased in higher glucose concentration in α -TC1 -6
