Predicted to enable lysine N-acetyltransferase activity, acting on acetyl phosphate as donor. Predicted to be involved in several processes, including amyloid-beta metabolic process; negative regulation of apoptotic process; and peptidyl-lysine N6-acetylation. Predicted to be located in endoplasmic reticulum membrane and endoplasmic reticulum-Golgi intermediate compartment membrane. Orthologous to human NAT8 (N-acetyltransferase 8 (putative)) and NAT8B (N-acetyltransferase 8B (putative, gene/pseudogene)). [provided by Alliance of Genome Resources, Apr 2022]
