IP Use at an assay dependent concentration.
WB 1/500. Detects a band of approximately 26 kDa (predicted molecular weight: 26 kDa).


  • Function
    GTP-binding protein involved in nucleocytoplasmic transport. Required for the import of protein into the nucleus and also for RNA export. Involved in chromatin condensation and control of cell cycle (By similarity). The complex with BIRC5/ survivin plays a role in mitotic spindle formation by serving as a physical scaffold to help deliver the RAN effector molecule TPX2 to microtubules.
    Enhances AR-mediated transactivation. Transactivation decreases as the poly-Gln length within AR increases.
  • Tissue specificity
    Expressed in a variety of tissues.
  • Sequence similarities
    Belongs to the small GTPase superfamily. Ran family.
  • Post-translational
    The N-terminus is blocked.
  • Cellular localization
    Nucleus. Cytoplasm. Melanosome. Becomes dispersed throughout the cytoplasm during mitosis. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

  • IHC image of ab4781 staining in human breast carcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab4781, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
