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. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. 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]
