Qkf, or K(lysine) acetyltransferase 6B, is a human gene encoded by KAT6B. It may also be known as: Histone acetyltransferase KAT6B; Histone acetyltransferase MOZ2; MOZ, YBF2/SAS3, SAS2 and TIP60 protein 4; MYST-4; Monocytic leukemia zinc finger protein-related factor; Histone acetyltransferase KAT6B ; MOZ-related factor; GTPTS; MORF; MOZ2; MYST4; ZC2HC6B; querkopf. The encoded protein is an enzyme with an amino acid length of 2073 and a mass of 231.4 kDa. Other isoforms may exist. Qkf is a member of the MYST (SAS/MOZ) family. Homologs of this gene exist in other organisms, including: Mouse.
