AURKA

The protein encoded by this gene is a cell cycle-regulated kinase that appears to be involved in microtubule formation and/or stabilization at the spindle pole during chromosome segregation. The encoded protein is found at the centrosome in interphase cells and at the spindle poles in mitosis. This gene may play a role in tumor development and progression. A processed pseudogene of this gene has been found on chromosome 1, and an unprocessed pseudogene has been found on chromosome 10. Multiple transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

Interaction

Interacts with FBXL7 (By similarity). Interacts with CPEB1, JTB, TACC1, TPX2, PPP2CA, as well as with the protein phosphatase type 1 (PP1) isoforms PPP1CA, PPP1CB and PPP1CC. Interacts also with its substrates ARHGEF2, BORA, KIF2A, PARD3, and p53/TP53. Interaction with BORA promotes phosphorylation of PLK1. Interacts with PIFO. Interacts with GADD45A, competing with its oligomerization. Interacts (via C-terminus) with AUNIP (via C-terminus). Identified in a complex with AUNIP and NIN. Interacts with FRY; this interaction facilitates AURKA-mediated PLK1 phosphorylation. Interacts with SIRT2 (PubMed:17726514, PubMed:22014574). Interacts with MYCN; interaction is phospho-independent and triggers AURKA activation; AURKA competes with FBXW7 for binding to unphosphorylated MYCN but not for binding to phosphorylated MYCN (PubMed:27837025). Interacts with HNRNPU (PubMed:21242313, PubMed:25986610). Interacts with AAAS (PubMed:26246606). Interacts with KLHL18 and CUL3 (PubMed:23213400). Interacts with FOXP1 (PubMed:28218735).
