has_part inheres_in abnormal mitotic spindle assembly checkpoint decreased response to mitotic spindle assembly checkpoint signaling A cellular process phenotype in which a mitotic cell cycle arrest that normally occurs in response to the mitotic spindle assembly checkpoint is decreased. The mitotic spindle assembly checkpoint normally delays the metaphase/anaphase transition of a mitotic nuclear division until the spindle is correctly assembled and chromosomes are attached to the spindle. In a mutant, the checkpoint may fail to arrest or delay cell cycle progression under appropriate conditions, or the incidence or duration of arrest or delay may differ from wild type under any specified set of conditions. decreased mitotic spindle assembly checkpoint during vegetative growth decreased spindle assembly checkpoint during mitotic cell cycle 2016-11-09T13:49:57Z FYPO:0005780 reduced response to mitotic spindle assembly checkpoint signaling midori decreased response to mitotic cell cycle spindle assembly checkpoint signaling
