Predicted to enable magnesium ion transmembrane transporter activity. Predicted to be involved in cognition; magnesium ion transport; and protein N-linked glycosylation via asparagine. Predicted to be located in endoplasmic reticulum. Predicted to be part of oligosaccharyltransferase complex. Used to study primary immunodeficiency disease. Human ortholog(s) of this gene implicated in X-linked immunodeficiency with magnesium defect, Epstein-Barr virus infection, and neoplasia; congenital disorder of glycosylation Icc; and non-syndromic X-linked intellectual disability. Orthologous to human MAGT1 (magnesium transporter 1). [provided by Alliance of Genome Resources, Apr 2022]
