STT3B

Dolichyl-diphosphooligosaccharide—protein glycosyltransferase subunit STT3B is an enzyme that in humans is encoded by the STT3B gene.[5][6][7]

Function

The STT3B protein contains a highly immunogenic minor histocompatibility antigen epitope of 9 amino acids, B6(dom1). Like ITM1 (MIM 601134), STT3B is homologous to yeast STT3, an oligosaccharyltransferase essential for cell proliferation.[8][7]
