HNRNPA2B1 and MALT lymphoma: In this study, a new specific 71S glycosylation site with the glycoform HexNAc(1) was observed in the HNRNPA2B1 protein from host cells infected by MALT lymphoma isolates, and the 259S site with the glycoform HexNAc(2)Hex(2)Fuc(2)NeuAc(1) was expressed steadily in only host cells and host cells infected by MALT lymphoma isolates, suggesting that these two specific glycosylation sites play an important role in the pathogenesis of MALT lymphoma caused by H. pylori infection.
