Magnesium transporter protein 1 (IPR006844)

Short name: Mg_transporter-1

Overlapping homologous superfamilies


Family relationships


Most eukaryotic organisms assemble heterooligomeric oligosaccharyltransferase (OST) complexes that consist of a catalytic subunit (an STT3 protein) plus several accessory subunits. Metazoan organisms express two STT3 proteins (STT3A and STT3B) [PMID: 19167329].

Magnesium transporter protein 1 (MagT1) is involved in N-glycosylation through its association with oligosaccharyltransferase, and could also be involved in Mg2+ transport in epithelial cells [PMID: 15804357, PMID: 19717468]. It is a subunit of the STT3B isoform of OST [PMID: 25135935].
