  • 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.

    Customer reviews and Q&As


    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 ( 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:
