FUNCTION: SwissProt: O14965 # May play a role in cell cycle regulation during anaphase and/or telophase, in relation to the function of the centrosome/spindle pole region during chromosome segregation. Maybe involved in microtubule formation and/or stabilization. May play a key role during tumor development and progression.
SIZE: 403 amino acids; 45809 Da
SUBUNIT: Interacts with TACC1 and CPEB1. Interacts with and phosphorylates BORA.
SUBCELLULAR LOCATION: Centrosome. Spindle. Note=Localizes on centrosomes in interphase cells and at each spindle pole in mitosis.
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. Expression is cell-cycle regulated, low in G1/S, accumulates during G2/M, and decreases rapidly after.
PTM: Phosphorylated upon DNA damage, probably by ATM or ATR.DISEASE:SwissProt: O14965 # Defects in AURKA are responsible for numerical centrosome aberrations including aneuploidy.
SIMILARITY: SwissProt: O14965 ## Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Aurora subfamily. & Contains 1 protein kinase domain.
