  • 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.

  • Immunocytochemistry with HeLa cells were stained with Anti-Nucleolin-488 antibody (0.2 µg/mL, ab154028) in green, Anti-GAPDH (1.0 µg/mL, ab110305) as red, and DAPI (1/10,000) in blue, as a nuclear stain. Secondary antibody used was goat anti-mouse IgG1 Alexa-594 at 1/1000 dilution. A) HeLa cells 40x. B) HeLa cells 100x.
  • Immunocytochemistry with HDFn cells were stained with Anti-Nucleolin-488 antibody (0.2 µg/mL, ab154028) in green, Anti-GAPDH (1.0 µg/mL, ab110305) as red, and DAPI in blue, as a nuclear stain. Secondary antibody used was goat anti-mouse IgG1 Alexa-594 at 1/1000 dilution. A) HDFn 40x. B) HDFn 100x.
