MeSH definition : Mad2 is a component of the spindle-assembly checkpoint apparatus. It binds to and
inhibits the Cdc20 activator subunit of the anaphase-promoting complex, preventing
the onset of anaphase until all chromosomes are properly aligned at the metaphase
plate. Mad2 is required for proper microtubule capture at KINETOCHORES.;
