Schematic diagram illustrating the role of IGFBP-6 phosphorylation and O -glycosylation on IGF-II functions. Here we propose that alternative O-β-GlcNAc modification and phosphorylation of Ser 204 control the binding of IGF-II with IGFBP-6 during viral infection, while mid region phosphorylation and O-β-GlcNAc modifications controls it's binding with glycosaminoglycans.
