Mad2, also known as MAD2, MAD2L1, or Mitotic spindle assembly checkpoint protein MAD2A, is a mitotic spindle assembly checkpoint protein. The spindle checkpoint makes sure that all the chromosomes are aligned at the metaphase plate before anaphase begins which means that all chromosomes are attached to the spindle before anaphase can start. The spindle checkpoint becomes triggered when the chromosome(s) are unaligned. Mad2 then binds to the anaphase promoting complex (APC) and CDC20. This complex prevents the cell from transitioning into anaphase and ultimately from cell death or disease.

Western Blotting Analysis: A representative lot from an independent laboratory detected Mad2 in HeLa cells transfected with pCMV expressing wild-type myc-tagged Mad2, and certain mutations of myc-tagged Mad2 (This mutant does not bind to the core of Mad1/Mad2) (De Antoni, A., et al. 2005. Curr Biol. 15(3):214-225.).
