  • Target

    • Function
      Contributes to the regulation of cell cycle progression. Required for normal mitosis. Associates with the centrosome and the spindle microtubules during mitosis and functions in centrosome maturation, spindle assembly, maintenance of spindle bipolarity, centrosome separation and mitotic checkpoint control. Phosphorylates numerous target proteins, including ARHGEF2, BRCA1, KIF2A, NDEL1, PARD3, PLK1 and BORA. Regulates KIF2A tubulin depolymerase activity (By similarity). Required for normal axon formation. Plays a role in microtubule remodeling during neurite extension. Important for microtubule formation and/or stabilization.
    • Tissue specificity
      Highly expressed in testis and weakly in skeletal muscle, thymus and spleen. Also highly expressed in colon, ovarian, prostate, neuroblastoma, breast and cervical cancer cell lines.
    • Sequence similarities
      Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Aurora subfamily.
      Contains 1 protein kinase domain.
    • Post-translational
      Activated by phosphorylation at Thr-288; this brings about a change in the conformation of the activation segment. Phosphorylation at Thr-288 varies during the cell cycle and is highest during M phase. Autophosphorylated at Thr-288 upon TPX2 binding. Phosphorylated upon DNA damage, probably by ATM or ATR.
      Ubiquitinated by CHFR, leading to its degradation by the proteasome (By similarity). Ubiquitinated by the anaphase-promoting complex (APC), leading to its degradation by the proteasome.
    • Cellular localization
      Cytoplasm > cytoskeleton > centrosome. Cytoplasm > cytoskeleton > spindle pole. Detected at the neurite hillock in developing neurons (By similarity). Localizes on centrosomes in interphase cells and at each spindle pole in mitosis.

    Thank you for your reply.

    I apologize for the confusion, there was a difference in the numerical order of amino acids listed in the alignment I was performing. You are correct, ab115883 should not be chosen as the immunogen sequence does not overlap with the Chlamy Aurora A sequence.

    I reran the search using the proper numerical organization and came up with the following antibody:
    ab61114 (https://www.abcam.com/Aurora-A-antibody-ab61114.html): the immunogen sequence is around the human Aurora A amino acid 288. The human and Chlamy sequences are quite homologous in this region, as amino acids 285 and 288 are the only two mismatched amino acids from 275-301.

    I'm actually confident enough in the homology within this region to offer our Abtrial program for testing ab61114 in your Chlamy sequences. Information regarding this program is given below:

    To our knowledge, ab61114 has not been tested in C. reinhardtii. However by participating in our AbTrial program you can now use our products in an untested application or species without financial risk.

    Additionally, until 12/16/12 we are running a rabbit monoclonal antibody promotion, our "RabMab" promotion, which entitles you to a free rabbit monoclonal antibody with purchase of a primary antibody. I found a rabbit monoclonal antibody ab108353 (https://www.abcam.com/Aurora-A-antibody-EPR5026-ab108353.html) that has 54% homology with the Chlamy sequence and might be worth a try, otherwise you could choose a different Rabbit monoclonal antibody that you desire. Details of the RabMab promotion are given below:

    Please let me know if you have any questions about this offer and I would be happy to help you further.

    Thank you for contacting Abcam.

    We discussed potential anti-Aurora A antibodies to detect Chlamydomonas reinhardtii Aurora A. Since C. reinhardtii Aurora A has 67.2% homology with human Aurora A, this does not qualify for our AbTrial program, but a positive or negative Abreview can be submitted explaining your experience to give you AbPoints which can be used for an amount off of a future purchase or Amazon gift cards.

    I searched through our anti-Aurora A antibodies, and ab115883 is likely your best option should you choose to proceed

    The immunogen for this antibody is from amino acids 268-277, which has a fair amount of alignment between human and C. reinhardtii Aurora A.
    Human: http://www.uniprot.org/uniprot/O14965
    C. reinhardtii: http://www.uniprot.org/uniprot/A8ISU1

    Additionally, we currently have a RabMab promotion running until 12/16/12, which entitles you to a Free Rabbit monoclonal antibody with any purchase of a primary antibody, while stocks last. Quote “RABMAB-XBSMG” in your next primary antibody order. For more information, visit the following link: https://www.abcam.com/index.html?pageconfig=resource&rid=15447

    To prepare my sample, I used a buffer containing 50mM Tris pH 7.5, 150mM NaCl, 1mM MgCl2 and 1% triton X-100. I included proteases inhibitors in the lysis buffer (complete edta-free tablet, from Roche). I incubated the cells 20 minutes with
    this buffer and then cleared the lysate by a 15 min centrifugation at 20 000g. I evaluated the protein concentration of my
    samples by the bradford method and then I added SDS-sample loading buffer to the lysates (containing DTT). I boiled the
    samples for 5 minutes.
    I suppose that the 8% acrylamide gel I used for SDS-PAGE is suitable for the experiment I performed since I see the 31kDa
    band of the marker, meaning that proteins around 48 kDA might still be in the gel, although I could also try with a 12%
    acrylamide gel.
    There was no SDS in my transfer buffer, only methanol, tris and glycine. I did a Ponceau coloration of the membrane to
    make sure the transfer worked well and everything was normal. I can also precise that I used these samples for other gels
    that were runned and transferred at the same time as the gel described for the western blot that did not worked with
    ab12875. I was able to detect 3 other proteins by Western blot, the only experiment that did not work was the one using
    ab12875 primary antibody. Those proteins had a size of 60, 55 and 42 kDa so there is no reason why I should not see Aurora A which is supposed to migrate at 48 kDa.
    We purchased this antibody less than one month ago so it might be possible that we request a credit. According to the catalog, Abcam sells other anti Aurora A antibodies that were reported to work well in western blot experiments so we would
    be interested in trying another one.

    Thank you for your reply.

    I would be happy to offer you a replacement antibody or a credit. Please let me know which you would prefer. If you would like an antibody, please include the catalogue number.

    I look forward to your reply.

    Thank you for taking time to contact us. I am sorry to hear that this antibody is not providing satisfactory results.

    The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality.

    Can you tell me a bit more about how you prepared your cell lysate? What kind of lysis buffer did you use? We would recommend NP-40 or RIPA buffer.

    Are you including protease inhibitors in with the sample preparation? I see that the samples are denatured, but are they reduced as well with b-mercaptoethanol or DTT? Did you boil the samples for 10 mins?

    Do you have access to a higher percentage gel? You may want to try a 12% gel for a protein below 50 kDa.

    For transfer of small proteins (< 100 kDa), consider removing SDS from the transfer buffer and keep the methanol concentration at 20%.

    Should the suggestions not improve the results, please do let me know.

    In the event that a product is not functioning in the species and applications cited on the product datasheet (and the problem has been reported within 6 months of purchase), we would be pleased to provide a free of charge replacement, credit note, or refund.

    I hope this information is helpful, and I thank you for your cooperation.
