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-mannosylprotein
CC (By similarity). 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 (PubMed:24256719). {ECO:0000250|UniProtKB:Q8NAT1,
CC ECO:0000269|PubMed:24256719}.
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:0000269|PubMed:24256719}.
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:Q8NAT1}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:Q8NAT1}.
CC -!- TISSUE SPECIFICITY: Mainly expressed in the central nervous system.
CC {ECO:0000269|PubMed:24256719}.
CC -!- DEVELOPMENTAL STAGE: Expressed during brain development. At 14.5 dpc,
CC expressed throughout the cortical plate and the developing brain, as
CC well as throughout the eye, including the lens and cornea. Cortical
CC expression is already detected at 12.5 dpc, peaks between 14.5 and 16.5
CC dpc and is reduced at birth. {ECO:0000269|PubMed:22958903}.
CC -!- DISRUPTION PHENOTYPE: Newborns are slightly smaller and die within the
CC first day of birth due to abnormal basal lamina formation and neuronal
CC migration defects. Defects are due to a lack of laminin-binding
CC glycans. {ECO:0000269|PubMed:24256719}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 61 family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAC31348.1; Type=Erroneous termination; Note=Truncated C-terminus.; Evidence={ECO:0000305};
CC Sequence=BAC35765.1; Type=Frameshift; Evidence={ECO:0000305};
