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. Has lower affinities for donors or acceptors than MGAT4A, suggesting that, under physiological conditions, it is not the main contributor in N- glycan biosynthesis. |Glyco transf 54| |alpha-1,3-mannosylglycoprotein 4-beta-N-acetylglucosaminyltransferase activity| |N-glycan processing| |acetylglucosaminyltransferase activity| |Golgi stack| |endoplasmic reticulum-Golgi intermediate compartment| |protein N-linked glycosylation| |macromolecule glycosylation| |protein glycosylation| |glycosylation| |glycoprotein biosynthetic process| |glycoprotein metabolic process| |carbohydrate derivative biosynthetic process| |Golgi membrane| |endoplasmic reticulum| |carbohydrate derivative metabolic process| |organonitrogen compound biosynthetic process| |cellular macromolecule biosynthetic process| |macromolecule biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp54|Taxol 0.002μM R01 exp54]]|-2.09| |[[:results:exp162|BI-D1870 2μM R04 exp162]]|-1.82| |[[:results:exp287|HMS-I2 5μM R06 exp287]]|-1.76| No correlation found to any other genes in chemogenomics.
