Cyclin dependent kinase 6 (complex with cyclin D3)

Synonyms: cell division protein kinase 6, PLSTIRE

Family: CMGC

CDK6 is a serine/threonine protein kinase and a member of cyclin dependent kinase family. CDK6 is closely related to CDK4 – both are cyclin D dependent kinases and are both active in the first gap phase (G1)1. It was proposed that CDK4/6-cyclin D complex phosphorylates the retinoblastoma tumour suppressor, causing it to dissociate from E2F transcription factors, affecting DNA replication and cell division2. The first selective inhibitor for CDK4 and CDK6 is Abemaciclib, which the safety and antitumor activity of abemaciclib as a single agent was demonstrated3.

CDK6-CYCLIND3 kinase assay is run on mobility shift microfluidics platform (Caliper), which provides best in industry quality of data. We routinely run services associated with this kinase including: screening, profiling, dose-response studies and kinetic measurements. Please contact us for more information.
