Kinesin ATPase Screening Services

Cyto pioneered kinesin screens—and we’ve spent decades mastering them. With published experts and unmatched in-house know-how, Cytos isn’t just a supplier—we’re the partner your drug discovery deserves.

Service overview: Kinesin ATPases

Kinesins are a family of molecular motors that utilize the energy of ATP hydrolysis to transport cargo such as chromosomes and vesicles along microtubule tracks. The central role of kinesins in cell division makes them an excellent target for anti-mitotics. Cytoskeleton’s screening service employs a colorimetric end-point assay and an absorbance-based kinetic assay to measure microtubule-stimulated kinesin ATPase activity. Incorporating rigorously validated, pre-formed microtubules, the service delivers highly reproducible, quantitative data suitable for all stages of drug development.

Case Study

Support in precision oncology

The objective

A Fortune 500 biopharmaceutical company required a comprehensive off-target counter-screen to evaluate the specificity of anti-kinesin drug candidates targeting KIF18A.

The result

Four compounds plus control inhibitors were tested in a motor panel consisting of KIF2, KIF3C, KIFC3, KIF4A, KIF10(CENPE), KIF11(Eg5), KIF20A, and KIF23. IC50’s confirmed that the compounds were highly specific to KIF18A and its close homologs KIF18B and KIF19A.

Some of the data generated by Cyto was included in a reported by Amgen Research company (CA, USA) and Broad Institute (MA, USA) in 2024 (Payton M. et al. Small-molecule inhibition of kinesin KIF18A reveals a mitotic vulnerability enriched in chromosomally unstable cancers. Nature Cancer. 5, 66-84 (2024): Extended data Fig 2).
