RL Submitted (NOV-2004) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Participates in O-mannosyl glycosylation by catalyzing the
CC addition of N-acetylglucosamine to O-linked mannose on glycoproteins.
CC Catalyzes the synthesis of the GlcNAc(beta1-2)Man(alpha1-)O-Ser/Thr
CC moiety on alpha-dystroglycan and other O-mannosylated proteins,
CC providing the necessary basis for the addition of further carbohydrate
CC moieties. Is specific for alpha linked terminal mannose.
CC {ECO:0000250|UniProtKB:Q8WZA1}.
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->2)-alpha-
CC D-mannosyl)-L-threonyl-[protein] + H(+) + UDP; Xref=Rhea:RHEA:54128,
CC Rhea:RHEA-COMP:13547, Rhea:RHEA-COMP:13802, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57705, ChEBI:CHEBI:58223, ChEBI:CHEBI:137323,
CC ChEBI:CHEBI:138067; Evidence={ECO:0000250|UniProtKB:Q8WZA1};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000250|UniProtKB:Q8WZA1};
CC Note=The manganese ion interacts primarily with the substrate UDP-N-
CC acetylglucosamine. {ECO:0000250|UniProtKB:Q8WZA1};
CC -!- PATHWAY: Protein modification; protein glycosylation.
CC {ECO:0000250|UniProtKB:Q8WZA1}.
CC -!- SUBUNIT: Interacts with DAG1 (via O-linked mannose moiety). Interacts
CC (via transmembrane domain) with FKTN; the interaction is direct and is
CC required for normal location in Golgi membranes.
CC {ECO:0000250|UniProtKB:Q8WZA1}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus membrane
CC {ECO:0000250|UniProtKB:Q8WZA1}; Single-pass type II membrane protein
CC {ECO:0000250|UniProtKB:Q8WZA1}.
CC -!- DOMAIN: The stem domain mediates specific interaction with beta-linked
CC N-acetylglucosamine moieties of O-glycosylated proteins. It also
CC interacts with its product, N-acetyl-beta-D-glucosaminyl-(1->2)-O-
CC alpha-D-mannosylprotein. {ECO:0000250|UniProtKB:Q8WZA1}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 13 family.
CC {ECO:0000305}.
