RIF1 suppresses the formation of single-stranded ultrafine anaphase bridges via protein phosphatase 1
Summary: Resolution of ultrafine anaphase bridges (UFBs) must be completed before cytokinesis to ensure sister-chromatid disjunction.RIF1 is involved in UFB resolution by a mechanism that is not yet clear.Here, we show that Micro Quads RIF1 functions in mitosis to inhibit the formation of 53BP1 nuclear bodies and micronuclei.Meanwhile, RIF1 localiz
