General description
Posttranslational modification of proteins by -linked N-acetylglucosamine ( -GlcNAc) via the hydroxyl moieties on serine or threonine residues is termed O-linked -GlcNAc or simply O-GlcNAc. O-GlcNAc is one of the most abundant posttranslational modifications within the nucleocytoplasmic compartments of all animals and plants. Unlike other types of protein glycosylations, O-GlcNAc occurs exclusively within the nuclear and cytoplasmic compartments and is generally not further modified to form more elongated structures. In addition, O-GlcNAcylation is a highly dynamic and reversible process. The O-GlcNAc transferase (OGT) attaches O-GlcNAc to proteins at specific serine or threonine residues, while O-GlcNAcase catalyzes the removal/hydrolysis of O-GlcNAc from proteins. In fact, a dynamic interplay between O-GlcNAcylation and serine/threonine phosphorylation plays an important role in regulating cellular signaling. Tau and RNA polymerase II (Pol II) are two well known proteins that undergo modification by O-GlcNAcylation. In Alzheimer s diseased human brains, tau becomes extensively phosphorylated and less O-GlcNAcylated. Similarly, O-GlcNAc is removed and replaced with O-phosphate on the Poly II CTD when the elongation phase of transcription is initiated.
Specificity
Both clone RL1 & clone RL2 (Cat. No. MABS157) target O-linked N-acetylglucosamine (GlcNAc) modified (GlcNAcylated) proteins. GlcNAc removal by beta-N-acetylglucosaminidase treatment or galactosylation of GlcNAc on target proteins by galactosyltransferase treatment greatly reduced the immunoreactivity of clone RL1 & RL2 toward their target proteins. The binding affinity of RL1 and RL2 toward a given GlcNAcylated protein is dependent on both O-GlcNAc and the adjacent core protein structure (Snow, C.M., et al. (1987). J. Cell Biol. 104(5):1143-11560; Holt, G.D., et al. (1987). J. Cell Biol. 104(5):1157-1164).
Target structure is not species-specific.

Application
Detect GlcNAcylated proteins using this mouse monoclonal Anti-O-GlcNAc, clone RL1 , Cat. No. MABS1253, validated for use in Affinity Binding, Electron Microscopy, Immunocytochemistry, Immunofluorescence, Immunohistochemistry, Immunoprecipitation, Inhibition, and Western Blotting.
Immunohistochemistry Analysis: A 1:50 dilution from a representative lot detected O-GlcNAcylated cytoplasmic and nuclear pore proteins in rat kidney and spleen tissue sections.
Affinity Binding Assay: A representative lot of clone RL1 & clone RL2 (Cat. No. MABS157) partially competed against each other for binding immobilized 180 kDa O-GlcNAcylated nuclear envelope protein (Snow, C.M., et al. (1987). J. Cell Biol. 104(5):1143-11560).
Electron Microscopy Analysis: A representative lot immunolocalized target proteins at the cytoplasmic and/or nucleoplasmic margins of the pore complex with no specific staining of the perinuclear space of isolated rat liver nuclear envelopes (Snow, C.M., et al. (1987). J. Cell Biol. 104(5):1143-11560).
Immunocytochemistry Analysis: Representative lots stained the nuclear envelope of paraformaldehyde-fixed, Triton X-100-permeabilized HeLa cells, NRK normal rat kidney epithelial cells and isolated rat liver nuclei by fluorescent immunocytochemistry (Yang, L., et al. (1997). J. Cell Biol. 139(5):1077-1087; Byrd, D.A., et al. (1994). J. Cell Biol. 127(6 Pt 1):1515-1526; Snow, C.M., et al. (1987). J. Cell Biol. 104(5):1143-11560).
Immunofluorescence Analysis: A representative lot stained the nuclear envelope proteins in formaldehyde-fixed, Triton X-100-permeabilzied salivary glands dissected from third-instar Drosophila larvae by fluorescent immunohistochemistry (Goldberg, M., et al. (1998). Mol. Cell. Biol. 18(7):4315-4323).
Immunofluorescence Analysis: Representative lots stained the nuclear envelope of methanol-fixed xenopus ovary and rat liver cryosections by fluorescent immunohistochemistry (Featherstone, C., et al. (1988). J. Cell Biol. 107(4):1289-1297; Snow, C.M., et al. (1987). J. Cell Biol. 104(5):1143-11560).
Immunoprecipitation Analysis: A representative lot immunoprecipitated several nuclear envelope proteins in salt-washed nuclear envelope preparations from rat liver and NRK normal rat kidney epithelial cells. Galactosylation of GlcNAc on nuclear envelope proteins by galactosyltransferase treatment significantly inhibited the immunoadsorption of these nuclear pore complex glycoproteins by clone RL1 (Snow, C.M., et al. (1987). J. Cell Biol. 104(5):1143-11560; Holt, G.D., et al. (1987). J. Cell Biol. 104(5):1157-1164).
Inhibition Analysis: A representative lot, when injected in the vegetal hemisphere of xenopus oocyte cytoplasm, inhibited nucleoplasmin nuclear import in a dose-dependent manner without affecting myoglobin nuclear import or RNA export (Featherstone, C., et al. (1988). J. Cell Biol. 107(4):1289-1297).
Western Blotting Analysis: Representative lots detected several nuclear envelope proteins in Xenopus oocyte nucleus extract and in salt-washed rat liver nuclear envelope preparations, including target bands of 210, 180, 145, 100, 63, 58, 54, and 45 kDa. GlcNAc removal by beta-N-acetylglucosaminidase treatment greatly reduced the detection of these nuclear pore complex glycoproteins by clone RL1 (Byrd, D.A., et al. (1994). J.
