Rabbit Anti-MGAT4C antibody
MGAT4C is a 478 amino acid single-pass type II membrane protein that localizes to the golgi apparatus and belongs to the glycosyltransferase 54 family. Expressed in liver, heart, testis, brain and adrenal gland, GnT-IVH functions as a glycosyltransferase that catalyzes the transfer of N-acetylglucosamine (GlcNAc) to the core mannose residues of N-linked glycans, thereby playing a crucial role in the production of tri- and tetra-antennary N-linked sugar chains. The gene encoding GnT-IVH maps to human chromosome 12, which encodes over 1,100 genes and comprises approximately 4.5% of the human genome.
Function:
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).
Subcellular Location:
Golgi apparatus membrane.
Tissue Specificity:
Expressed in heart, adrenal gland, testis, liver, brain and fetal brain. Not expressed in pancreas.
Similarity:
Belongs to the glycosyltransferase 54 family.
