    • Function

      Nucleolin is the major nucleolar protein of growing eukaryotic cells. It is found associated with intranucleolar chromatin and pre-ribosomal particles. It induces chromatin decondensation by binding to histone H1. It is thought to play a role in pre-rRNA transcription and ribosome assembly. May play a role in the process of transcriptional elongation. Binds RNA oligonucleotides with 5'-UUAGGG-3' repeats more tightly than the telomeric single-stranded DNA 5'-TTAGGG-3' repeats.
    • Sequence similarities

      Contains 4 RRM (RNA recognition motif) domains.
    • Post-translational

      Some glutamate residues are glycylated by TTLL8. This modification occurs exclusively on glutamate residues and results in a glycine chain on the gamma-carboxyl group.
    • Cellular localization

      Nucleus > nucleolus. Cytoplasm. Localized in cytoplasmic mRNP granules containing untranslated mRNAs.

    • All lanes : Anti-Nucleolin antibody [EPR7951] (ab134164) at 1/10000 dilution

      Lane 1 : Wild-type HeLa whole cell lysate
      Lane 2 : Nucleolin knockout HeLa whole cell lysate
      Lane 3 : MCF7 whole cell lysate

      Lysates/proteins at 20 µg per lane.

      Predicted band size: 76 kDa
      Observed band size: 100 kDa
      why is the actual band size different from the predicted?

      Lanes 1 - 3: Merged signal (red and green). Green - ab134164 observed at 100 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab134164 was shown to specifically react with Nucleolin in wild-type HeLa cells as signal was lost in Nucleolin knockout cells. Wild-type and Nucleolin knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% Milk. ab134164 and ab8245 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/10000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
