  • 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.

  • ab61114 staining Aurora A in human ovarian carcinoma.
    Left panel: with primary antibody at 4 ug/ml. Right panel: isotype control.
    Sections were stained using an automated system (DAKO Autostainer Plus ), at room temperature: sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffers citrate pH6.1 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that for manual staining we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.
  • ab61114 staining Aurora A in Human Fibroblast cells by Immunocytochemistry/Immunofluorescence. Cells were PFA-fixed and permeabilized in methanol for 30 minutes at -20°C prior to blocking in 20% FCS for 30 minutes at room temperature. The primary antibody was diluted 1/500 with the blocking buffer and incubated with the sample for 1 hour. The secondary antibody was a Alexa Fluor 594® conjugated Goat anti-Mouse polyclonal, diluted 1/1000.
    DAPI was used for the nuclear counterstain.

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:

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.
