The MYST HAT Sas2 is part of the SAS-I complex. The target for acetylation by Sas2 is Lys16 of histone H4 (H4 K16Ac). This acetylation site marks euchromatic regions and opposes the spreading of heterochromatin at telomere-proximal regions. Changes of SAS-I-mediated H4 K16Ac on a genome-wide scale c...
