KAT8 (MOF, MYST1) is a member of the MYST (Moz-Ybf2/Sas3-Sas2-Tip60) family of histone acetyltransferases (HATs). KAT8 is the catalytic component of the nine-subunit non-specific lethal (NSL) complex (Mendjan et al. 2006, Cai et al. 2010).

NSL acetylates histone H4 on lysines 17 (H4K16), 6 (H4K5) and 9 (H4K8) (Cai et al. 2010).

KAT8 is also the catalytic subunit of the male-specific lethal (MSL) complex, which acetylates almost exclusively H4K16 and is responsible for a large fraction of H4K16 acetylation in human cells (Smith et al. 2005).

N.B. Coordinates of post-translational modifications described here follow UniProt standard practice whereby coordinates refer to the translated protein before any further processing. Histone literature typically refers to coordinates of the protein after the initiating methionine has been removed. Therefore the coordinates of post-translated residues in the Reactome database and described here are frequently +1 when compared with the literature.
