Abstract

The addition of O-linked N-acetylglucosamine (GlcNAc) to the major nuclear pore complex glycoprotein p62 was examined. Expression of the rat p62 cDNA in transfected monkey cells was detected using a rat p62-specific antipeptide antiserum and two previously described nuclear pore-specific monoclonal antibodies which require O-linked GlcNAc for binding. Although the p62 cDNA was predicted to encode a 54-kDa polypeptide, the product expressed in monkey cells migrated on sodium dodecyl sulfate-polyacrylamide gel electrophoresis as two species of 62 and 59-kDa. Cell-free translation of the p62 in vitro transcript yielded a 59-kDa polypeptide using wheat germ extract and a 62-kDa product using a commercially available rabbit reticulocyte lysate. Several lines of evidence indicated that the 62-kDa rabbit reticulocyte lysate translation product was modified by O-linked N-acetylglucosamine; the protein bound specifically to a wheat germ agglutinin affinity column and was converted to 59 kDa when treated with jack bean beta-acetylglucosaminidase. The 59-kDa unglycosylated wheat germ translation product was converted to the 62-kDa glycosylated form upon incubation with reticulocyte lysate demonstrating that O-linked GlcNAc can be added to p62 post-translationally.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
