BUB3は紡錘体チェックポイント（SAC）の調節に関与するタンパク質であり、酵母では必須ではないが、高等真核生物では必須である。チェックポイントタンパク質の1つとして、BUB3は前中期の間に他のタンパク質のキネトコアへの局在を指揮し、後期の不可逆的開始を防いでいる。BUB3はキネトコア-微小管間の相互作用を指揮することで、後期が開始される前に染色体が適切な二方向型（biorientation）の接着を行うよう保証している。BUB3とその関連タンパク質は紡錘体チェックポイントを構成して後期促進複合体（APC/C）の作用を阻害し、時期尚早な後期の開始と有糸分裂の終結を防いでおり、染色体分離の正確性を高める機構として機能している^[7]。
