UniProt ID: Q7ZV50 |
FUNCTION: Cell surface magnesium transporter. {ECO:0000269|PubMed:19717468}. FUNCTION: Accessory component of the STT3B-containing form of the N- oligosaccharyl transferase (OST) complex which catalyzes the transfer of a high mannose oligosaccharide from a lipid-linked oligosaccharide donor to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains. May be involved in substrate-specific N- glycosylation. {ECO:0000250|UniProtKB:Q9H0U3}. PATHWAY: Protein modification; protein glycosylation. {ECO:0000250|UniProtKB:Q9H0U3}. SUBUNIT: Accessory component of the STT3B-containing form of the oligosaccharyltransferase (OST) complex. {ECO:0000250|UniProtKB:Q9H0U3}. SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q9H0U3}; Multi-pass membrane protein {ECO:0000250|UniProtKB:Q9H0U3}. Endoplasmic reticulum {ECO:0000250|UniProtKB:Q9H0U3}. Endoplasmic reticulum membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. DISRUPTION PHENOTYPE: Early developmental arrest. {ECO:0000269|PubMed:19717468}. SIMILARITY: Belongs to the OST3/OST6 family. {ECO:0000305}. |
