CC -!- FUNCTION: O-linked mannose beta-1,4-N-acetylglucosaminyltransferase
CC that transfers UDP-N-acetyl-D-glucosamine to the 4-position of the
CC mannose to generate N-acetyl-D-glucosamine-beta-1,4-O-D-
CC mannosylprotein. Involved in the biosynthesis of the phosphorylated O-
CC mannosyl trisaccharide (N-acetylgalactosamine-beta-3-N-
CC acetylglucosamine-beta-4-(phosphate-6-)mannose), a carbohydrate
CC structure present in alpha-dystroglycan (DAG1), which is required for
CC binding laminin G-like domain-containing extracellular proteins with
CC high affinity (By similarity). {ECO:0000250|UniProtKB:Q8NAT1}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=3-O-(alpha-D-mannosyl)-L-threonyl-[protein] + UDP-N-acetyl-
CC alpha-D-glucosamine = 3-O-(N-acetyl-beta-D-glucosaminyl-(1->4)-alpha-
CC D-mannosyl)-L-threonyl-[protein] + H(+) + UDP; Xref=Rhea:RHEA:37663,
CC Rhea:RHEA-COMP:13547, Rhea:RHEA-COMP:13618, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57705, ChEBI:CHEBI:58223, ChEBI:CHEBI:137323,
CC ChEBI:CHEBI:137540; EC=2.4.1.312;
CC Evidence={ECO:0000250|UniProtKB:Q8NAT1};
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC {ECO:0000250|UniProtKB:Q8NAT1}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q8NAT1}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:Q8NAT1}.
CC -!- DEVELOPMENTAL STAGE: Expressed in the embryo and larva throughout
CC development, with highest levels in the developing brain, eyes and at
CC the boundaries between somites. {ECO:0000269|PubMed:22958903}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 61 family.
CC {ECO:0000305}.
