One application of this principle has been in the fabrication of protein microarrays, a subset o...

A team of rivals at the kinetochore P rotein phosphatase I (PPI) is specifically recruited to kinetochores to counteract the Aurora B kinase, report Liu et al. The opposing enzymes combine to ensure chromosomes segregate correctly in mitosis. In metaphase, the kinetochores of sister chromatids must connect to microtubules emanating from opposite spindle poles. Incorrect attachments are eliminat...
