RanBPM is associated with microtubules.

<p><b>A)</b> Hela and <b>B)</b> 3T3 MEFs were fixed and incubated with antibodies against RanBPM and α-tubulin. Shown are single plane confocal images. Insets are enlarged images of the boxed regions from the above panels and arrows indicate areas of colocalization. The right panels show merged images (RanBPM, green; α-tubulin, red). Scale bar: 10μm. <b>C)</b> Hela whole cell extracts were incubated with either an α-tubulin antibody or mouse IgG control. Immunoprecipitates were analyzed by western blot using RanBPM and α-tubulin antibodies and compared with 5% of input proteins.
