Predicted to enable O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase activity. Predicted to be involved in marginal zone B cell differentiation and regulation of Notch signaling pathway. Predicted to act upstream of or within blastocyst formation; positive regulation of Notch signaling pathway; and positive regulation of protein binding activity. Predicted to be integral component of membrane. Orthologous to human MFNG (MFNG O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
