  • Function

    Acts as a cofactor for XPO1/CRM1-mediated nuclear export, perhaps as export complex scaffolding protein. Bound to XPO1/CRM1, stabilizes the XPO1/CRM1-cargo interaction. In the absence of Ran-bound GTP prevents binding of XPO1/CRM1 to the nuclear pore complex. Binds to CHC1/RCC1 and increases the guanine nucleotide exchange activity of CHC1/RCC1. Recruits XPO1/CRM1 to CHC1/RCC1 in a Ran-dependent manner. Negative regulator of TGF-beta signaling through interaction with the R-SMAD proteins, SMAD2 and SMAD3, and mediating their nuclear export.
  • Tissue specificity

    Widely expressed with high levels in testis and heart.
  • Sequence similarities

    Contains 1 RanBD1 domain.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

    Cytoplasm. Nucleus.

  • Immunohistochemistry of Human clear cell carcinoma of kidney tissues staining RanBP3 using ab134052 (1/1000). a HRP conjugated Goat Anti-Rabbit IgG H&L was used as a secondary antibody. 

    Antigen retrieval performed using heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).

    Predicted band size: 60 kDa
    Observed band size: 70,90 kDa
    why is the actual band size different from the predicted?

    Exposure time: 180 seconds

    The double bands are consistent with what has been described in PMID 16314428.

    We are unsure how to define the extra bands.
