Antibodies to O-GlcNAc modified proteins and peptides
O-glycosylation on the serine and threonine of proteins by a single N-acetyl-D-glucosamine moiety (O-GlcNAc) is a post-translational modification that is highly dynamic and fluctuates in response to a wide range of stimuli. This type of glycosylation has been found on hundreds of human proteins and is thought to be nearly as wide-spread as protein phosphorylation. Interestingly, multiple reports have demonstrated a reciprocal regulatory relationship between O-GlcNAc and phosphorylation, which occupy the same or adjacent serine/threonine sites on proteins, share extensive crosstalk, and contribute to many different human disease mechanisms.
To facilitate the study of this modification and its dynamics, GlycoScientific has developed a range of site-specific antibodies that have a high preference for the O-GlcNAcylated species, we refer to this as glycophilic antibodies. We have also generated antibodies that recognize the site with or without the O-GlcNAc. The combination of these antibodies lets one determine changes in the extent of occupancy. Visit our Antibodies to O-GlcNAc page for a complete list of glycophilic and non-preferential antibodies and corresponding peptides organized by target protein.
