Our Abpromise guarantee covers the use of ab74473 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
WB Use a concentration of 1 µg/ml. Detects a band of approximately 38 kDa (predicted molecular weight: 31 kDa).
ICC/IF Use at an assay dependent concentration.


  • Function

    Component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. The CPC complex has essential functions at the centromere in ensuring correct chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly. In the complex, it may be required to direct the CPC to centromeric DNA. Major effector of the TTK kinase in the control of attachment-error-correction and chromosome alignment.
  • Sequence similarities

    Belongs to the borealin family.
  • Developmental stage

    Cell-cycle regulated. Increases during G2/M phase and then reduces after exit from M phase.
  • Domain

    The C-terminal region (aa 207-280) represents the dimerization motif.
  • Post-translational

    Phosphorylated by TTK, essentially at Thr-88, Thr94, Thr-169 and Thr-230.
    Sumoylated by UBE2I and RANBP2. Desumoylated by SENP3 through the removal of SUMO2 and SUMO3.
  • Cellular localization

    Nucleus > nucleolus. Cytoplasm. Cytoplasm > cytoskeleton > spindle. Chromosome > centromere. Localizes on chromosome arms and inner centromeres from prophase through metaphase and then transferring to the spindle midzone and midbody from anaphase through cytokinesis. Colocalizes with SENP3 in the nucleolus in interphase cells.

Thank you very much for your call today and for letting us know about the trouble with these antibodies.

I am very sorry that these antibodies did not work as stated on the datasheet. As we discussed, I'm sending ab70910 free of charge on the order ***which should arrive on Wednesday, and also ab134112 on the order *** which we expect to arrive on Friday.

Please keep me updated about the results with these replacement antibodies, and let me know if there is anything else that we can do for you.
