Enables glucosamine 6-phosphate N-acetyltransferase activity. Acts upstream of or within cellular response to leukemia inhibitory factor. Located in Golgi apparatus; endoplasmic reticulum-Golgi intermediate compartment; and late endosome. Is expressed in several structures, including alimentary system; brain; integumental system; respiratory system; and sensory organ. Orthologous to human GNPNAT1 (glucosamine-phosphate N-acetyltransferase 1). [provided by Alliance of Genome Resources, Apr 2022]
