Alpha-1,3-mannosyl-glycoprotein 4-beta-N-acetylglucosaminyltransferase A

UniProtKB accession:  Q812G0

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Glycosyltransferase that catalyze the transfer of GlcNAc from UDP-GlcNAc to the GlcNAcbeta1-2Manalpha1-3 arm of the core structure of N-linked glycans through a beta1-4 linkage and participates in the production of tri- and tetra-antennary N-linked sugar chains (PubMed:16377570). Involved in glucose transport by mediating SLC2A2/GLUT2 glycosylation, thereby controlling cell-surface expression of SLC2A2 in pancreatic beta cells (PubMed:16377570).
