CC -!- FUNCTION: Glycosyltransferase that catalyze the transfer of GlcNAc from
CC UDP-GlcNAc to the GlcNAcbeta1-2Manalpha1-3 arm of the core structure of
CC N-linked glycans through a beta1-4 linkage and participates in the
CC production of tri- and tetra-antennary N-linked sugar chains (By
CC similarity). Involved in glucose transport by mediating SLC2A2/GLUT2
CC glycosylation, thereby controlling cell-surface expression of SLC2A2 in
CC pancreatic beta cells (By similarity). {ECO:0000250|UniProtKB:O77836,
CC ECO:0000250|UniProtKB:Q812G0}.
