Predicted to enable enzyme activator activity. Predicted to be involved in several processes, including T cell activation; protein N-linked glycosylation via asparagine; and regulation of protein stability. Predicted to be located in endoplasmic reticulum. Predicted to be part of oligosaccharyltransferase complex. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation Ir. Orthologous to human DDOST (dolichyl-diphosphooligosaccharide--protein glycosyltransferase non-catalytic subunit). [provided by Alliance of Genome Resources, Apr 2022]
