Product Overview
This rabbit polyclonal antibody targets ran-specific GTPase-activating protein (gene RANBP1) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 23.3 kDa, and the supplier reports an observed band at about 27 kDa.
RanBP1 (RANBP1) is a cytoplasmic Ran-binding protein that helps release Ran-GTP from import and export receptors. It thereby supports RanGAP-driven GTP hydrolysis and the recycling of transport factors in nucleocytoplasmic transport, and it also influences mitotic spindle function.
