Gene Snapshot

mad2 (mad2) encodes a conserved component of the spindle checkpoint. During mitosis, it is recruited to unattached kinetochores, where it binds the products of Mad1 and fzy, promoting the assembly of the mitotic checkpoint complex. During interphase, the product of mad2 is intranuclear, bound to the product of Mad1, and associated primarily with the nuclear pore complex. [Date last reviewed: 2019-03-14]

Summary (Interactive Fly)

mitotic checkpoint protein that blocks mitotic exit by sequestering Cdc20/Fizzy - required to delay progression through early stages of prometaphase so that cells have time to fully engage the spindle assembly checkpoint
