Anti-TTK/Mps1/TTK Antibody Picoband® Fluoro488 Conjugated

Dual specificity protein kinase TTK is a protein that in humans is encoded by the XRCC2 gene. This gene is mapped to 6q14.1. 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.

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