Summaries for TTK Gene

Entrez Gene Summary for TTK Gene

  • This gene encodes a dual specificity protein kinase with the ability to phosphorylate tyrosine, serine and threonine. Associated with cell proliferation, this protein is essential for chromosome alignment at the centromere during mitosis and is required for centrosome duplication. It has been found to be a critical mitotic checkpoint protein for accurate segregation of chromosomes during mitosis. Tumorigenesis may occur when this protein fails to degrade and produces excess centrosomes resulting in aberrant mitotic spindles. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2009]

GeneCards Summary for TTK Gene

TTK (TTK Protein Kinase) is a Protein Coding gene. Among its related pathways are Cell Cycle / Checkpoint Control and RB in Cancer. GO annotations related to this gene include identical protein binding and protein tyrosine kinase activity. An important paralog of this gene is TLK1.

UniProtKB/Swiss-Prot for TTK Gene

  • 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.
