Web1 mrt. 2001 · Mad1 was first identified in budding yeast as an essential component of the checkpoint system that monitors spindle assembly in mitosis and prevents premature anaphase onset. Using antibodies to the human homologue of Mad1 (HsMAD1), we have begun to characterize this protein in mammalian cells. HsMad1 is found localized at … WebMad2 (mitotic arrest deficient 2) is an essential spindle checkpoint protein. The spindle …
