Predicted to enable alpha-1,6-mannosylglycoprotein 6-beta-N-acetylglucosaminyltransferase activity; manganese ion binding activity; and protein phosphatase inhibitor activity. Predicted to be involved in several processes, including negative regulation of protein tyrosine phosphatase activity; positive regulation of receptor signaling pathway via STAT; and protein N-linked glycosylation via asparagine. Predicted to be located in Golgi membrane. Predicted to be active in Golgi apparatus. Used to study proteinuria. Orthologous to human MGAT5 (alpha-1,6-mannosylglycoprotein 6-beta-N-acetylglucosaminyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
