MGAT4C (MGAT4 Family Member C) is a Protein Coding gene. Diseases associated with MGAT4C include Mannosidosis, Beta and Muscular Dystrophy, Congenital. Among its related pathways are Transport to the Golgi and subsequent modification and Metabolism of proteins. GO annotations related to this gene include transferase activity, transferring hexosyl groups and alpha-1,3-mannosylglycoprotein 4-beta-N-acetylglucosaminyltransferase activity. An important paralog of this gene is MGAT4A. Glycosyltransferase that participates in the transfer of N-acetylglucosamine (GlcNAc) to the core mannose residues of N-linked glycans. Catalyzes the formation of the GlcNAcbeta1-4 branch on the GlcNAcbeta1-2Manalpha1-3 arm of the core structure of N-linked glycans. Essential for the production of tri- and tetra-antennary N-linked sugar chains (By similarity). Does not catalyze the transfer of GlcNAc to the Manalpha1-6 arm to form GlcNAcBeta1-4Manalpha1-6 linkage (GnT-VI activity).
