Our Abpromise guarantee covers the use of ab2938 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use a concentration of 10 µg/ml.

Immunohistochemical staining of bovine retina results in cytoplasmic staining of cells within the inner nuclear layer as well as the ganglion cells.

WB Use a concentration of 1 µg/ml. Detects a band of approximately 360 kDa (predicted molecular weight: 358 kDa).Can be blocked with RanBP2 peptide (ab4939).

Detects a band of approximately 360 kDa representing RanBP 2 from bovine retinal extracts.


  • Function
    E3 SUMO-protein ligase which facilitates SUMO1 and SUMO2 conjugation by UBE2I. Involved in transport factor (Ran-GTP, karyopherin)-mediated protein import via the F-G repeat-containing domain which acts as a docking site for substrates. Could also have isomerase or chaperone activity and may bind RNA or DNA. Component of the nuclear export pathway. Specific docking site for the nuclear export factor exportin-1.
  • Pathway
    Protein modification; protein sumoylation.
  • Involvement in disease
    Defects in RANBP2 are the cause of susceptibility to encephalopathy acute necrotizing type 1 (ANE1) [MIM:608033]. A rapidly progressive encephalopathy manifesting in susceptibile individuals with seizures and coma. It can occur within days in otherwise healthy children after common viral infections such as influenza and parainfluenza, without evidence of viral infection of the brain or inflammatory cell infiltration. Brain T2-weighted magnetic resonance imaging reveals characteristic symmetric lesions present in the thalami, pons and brainstem.
  • Sequence similarities
    Contains 1 PPIase cyclophilin-type domain.
    Contains 4 RanBD1 domains.
    Contains 8 RanBP2-type zinc fingers.
    Contains 1 TPR repeat.
  • Domain
    Contains F-X-F-G repeats.
  • Post-translational
    Polyubiquitinated by PARK2, which leads to proteasomal degradation.
  • Cellular localization
    Nucleus > nuclear pore complex. Cytoplasmic filaments.
