Recombinant Human Dual specificity protein kinase TTK (TTK), Truncated

Uniprot Id

P33981

Target Species

Human

Target Name

TTK

Target Full Name

Dual specificity protein kinase TTK

Target Function

Phosphorylates proteins on serine, threonine, and tyrosine. Probably associated with cell proliferation. Phosphorylates MAD1L1 to promote mitotic checkpoint signaling. Essential for chromosome alignment by enhancing AURKB activity (via direct CDCA8 phosphorylation) at the centromere, and for the mitotic checkpoint.

Target Protein Families

Protein kinase superfamily, Ser/Thr protein kinase family

Target Tissue Specificity

Present in rapidly proliferating cell lines.

Target Background

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.
