Mgat4 May Play a Role in Increased Sialylation by Overexpressing Functional MGAT1 in Mgat1-Disrupted Chinese Hamster Ovary (CHO) Cells

MGAT1 adds N-acetylglucosamine to the Man5GlcNAc2 (Man5) structure. Goh et al. reported increased sialylation after restoring MGAT1 function in MGAT1 deficient CHO cells.
