Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables alpha-1,3-mannosylglycoprotein 4-beta-N-acetylglucosaminyltransferase activity. Involved in N-glycan processing. Acts upstream of or within protein N-linked glycosylation. Predicted to be located in Golgi apparatus; extracellular region; and membrane. Predicted to be active in Golgi stack; endoplasmic reticulum; and endoplasmic reticulum-Golgi intermediate compartment. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; nose; and respiratory system. Orthologous to human MGAT4A (alpha-1,3-mannosyl-glycoprotein 4-beta-N-acetylglucosaminyltransferase A).
