    basic FUNCTION
  • mitotic spindle assembly checkpoint gene
  • modulating the timing of anaphase initiation in mitotic cells with improperly aligned chromosomes
  • promotes the formation of stable end-on bipolar attachments
  • required for regulation of both meiosis I and II, and is potentially involved in kinetochore-microtubule attachment in mammalian oocytes
  • together with BUB1, has a specific function in promoting the conversion from chromosome mono-orientation to bi-orientation
  • mediator protein inducing caspase-independent mitotic death in response to kinetochore–microtubule attachment defects
  • CELLULAR PROCESS cell cycle, division, mitosis
    cell cycle, checkpoint
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • heterodimerizing and recruiting to the kinetochore with BUB1 or BUB1B anaphase promoting complex
  • member of the SAC complex (spindle assembly checkpoint)
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • BUB1 or BUB1B
  • linking DYNLT3
  • interacting with TP73 (has a role in regulating SAC functions during meiosis and mitosis)
  • BUB1 interactor and a spindle checkpoint protein
  • interacts with TP73 specifically in cells in which CIMD (caspase-independent mitotic death) occurs
  • cell & other
