== Function ==
[https://www.uniprot.org/uniprot/TTK_HUMAN TTK_HUMAN] Phosphorylates proteins on serine, threonine, and tyrosine. Probably associated with cell proliferation. Essential for chromosome alignment by enhancing AURKB activity (via direct CDCA8 phosphorylation) at the centromere, and for the mitotic checkpoint.<ref>PMID:18243099</ref>

== Publication Abstract from PubMed ==
Triple-negative breast cancer (TNBC) is an aggressive breast-cancer subtype associated with poor prognosis and high relapse rates. Monopolar spindle 1 kinase (MPS1) is an apical dual-specificity protein kinase that is over-expressed in TNBC. We herein report a highly selective MPS1 inhibitor based on a 7H-pyrrolo[2,3-d]pyrimidine-5-carbonitrile scaffold. Our lead optimization was guided by key X-ray crystal structure analysis. In vivo evaluation of candidate (9) is shown to effectively mitigate human TNBC cell proliferation.
