Dolichyl-diphosphooligosaccharide–protein glycosyltransferase subunit STT3B is an enzyme that in humans is encoded by the STT3B gene.The SIMP protein contains a highly immunogenic minor histocompatibility antigen epitope of 9 amino acids B6(dom1). Like ITM1 (MIM 601134) SIMP is homologous to yeast STT3 an oligosaccharyltransferase essential for cell proliferation (McBride et al. 2002).[supplied by OMIM]
