Probable histone acetyltransferase (Probable). Required to initiate and then maintain lateralized gene expression in the ASE sensory neurons (PubMed:20923973). Involved in determining cell fate in the ASE neurons (PubMed:20923973). acetyl-CoA + L-lysyl-[protein] = CoA + H(+) + N(6)-acetyl-L-lysyl-[protein] Belongs to the MYST (SAS/MOZ) family.
