The O-GlcNAc ELISA kits listed below are analytical tools for measuring concentrations of O-GlcNAc in various samples. O-GlcNAc is an alternative name for the human OGT gene, which encodes the protein, O-linked N-acetylglucosamine (GlcNAc) transferase. It has been mentioned that O-GlcNAc plays a role in the apoptotic pathway and chromatin organization, among other functions. Structurally, the OGT protein is 1046 amino acid residues in length and 116.9 kilodaltons in mass. However, as many as 4 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is reported to be highly expressed in pancreas and to a lesser extent in skeletal muscle, heart, brain and placenta. This protein is known to be glycosylated, ubiquitinated and phosphorylated. Other names for this target antigen include HINCUT-1, HRNT1, and MRX106.
